Complete POTA Setup: Radio, Antenna, and Power for Park Activations

Building a POTA Station That Actually Works Together

Parks on the Air has exploded since 2020 — over 100,000 activations in 2023 alone — and the gear market has responded with more portable options than ever. But here's what nobody tells you in product reviews: individual gear choices matter less than how your components work together. A 100W radio paired with a battery that can't sustain it, or a resonant antenna connected to a rig that demands an external tuner — these mismatches turn a fun activation into a frustrating one.

Street prices in this article were checked in July 2026 and move around; verify with a dealer such as HRO, DX Engineering, or GigaParts before you buy.

I've done over 200 POTA activations across 45 parks since 2021. I've dialed in three complete setups at different price points, and I'll share exactly what works together and why. Each setup is a tested combination — radio, antenna, feedline, battery, and accessories — that I'd hand to a friend and say "this will work, go activate."

Setup 1: The Budget Workhorse ($600-800 Total)

This is what I recommend to every new POTA activator. It's light enough for a short hike, powerful enough for easy activations, and cheap enough that you won't cry if it rains.

Radio: Xiegu G90 ($450)

20 watts on all HF bands (160-10m, no 6m), built-in antenna tuner, built-in spectrum display. The G90 hits a sweet spot for POTA: enough power to be heard without needing a massive battery, and the internal tuner means your antenna doesn't need to be perfectly resonant. It's not fancy — the menus are clunky, the display is small — but it transmits clean signal and receives well enough for park activations where you're typically the loudest station in the pile.

Why this over a QRP rig at this price? Because 20 watts versus 5 watts is the difference between a 15-minute activation and a 45-minute grind. On a busy POTA frequency with QRM from adjacent stations, those extra 6 dB make contacts significantly easier. You can always turn it down.

Antenna: EFHW-4010 End-Fed Half-Wave ($75-110)

A linked end-fed half-wave for 40 and 20 meters. You can build one for $30 in parts (49:1 transformer, wire, connectors) or buy a commercial one from MyAntennas, Packtenna, or LNR Precision. I recommend the commercial option for beginners — a properly wound transformer with tested SWR matters more when you're learning.

Why 40 and 20 meters? Because those two bands account for roughly 80% of all POTA contacts. 40 meters covers regional (300-1,500 miles) daytime and long-distance nighttime. 20 meters covers DX and long-haul domestic. With just these two bands, you'll never fail to get your 10 contacts for a valid activation.

Deployment: Throw a line over a tree branch at 30+ feet, hoist the far end of the wire up, run it at a slope to your operating position. The feedpoint (transformer) stays at your table. Total setup time with practice: 8-12 minutes.

Feedline: 6 feet of RG-316 ($15)

Just a short coax jumper from the antenna transformer to the radio. End-fed half-waves are fed at a high-impedance point that the 49:1 transformer brings down to approximately 50 ohms — you don't need (or want) a long feedline run. Six feet is enough to position the transformer away from the radio to reduce common-mode noise.

Add a choke: Wind 8-10 turns of RG-316 on an FT-240-43 toroid at the radio end. Common-mode current on EFHW antennas is real and can cause RF in the shack (or on your picnic table). A $12 choke fixes it.

Battery: Bioenno BLF-1209A 9Ah LiFePO4 ($110)

12V, 9 amp-hours, 2.6 pounds. At 20 watts SSB, the G90 draws about 4 amps on transmit and 0.4 amps on receive. For a typical 1-hour activation with 30% duty cycle (SSB), you'll use roughly 2-3 Ah. This battery gives you three full activations before recharging — or one very long activation if conditions are rough.

Why LiFePO4? Flat discharge curve (stays near 13.2V until nearly empty, so your radio output stays consistent), safe chemistry (no thermal runaway), 2000+ cycle life, lighter than lead-acid. The Bioenno BLF-1209A specifically because it has Anderson Powerpole connectors pre-installed and the form factor fits perfectly under the G90.

Accessories

• Arborist throw line + 8oz weight ($20): For getting your antenna wire over tree branches. Way better than throwing rocks tied to string.
• Lightweight folding table and chair ($40-60): You're going to be operating for 30-60 minutes minimum. A camp chair saves your back.
• Paper log + pencil ($5): Yes, paper. Electronics fail in cold/heat/rain. Log contacts on paper, enter them into POTA.app later.
• Earbuds or small headphones ($15): Hearing weak stations over park ambient noise (wind, birds, kids screaming) requires headphones. Don't skip this.

Total weight: approximately 8 pounds including all accessories, excluding table/chair.
Total cost: $650-800 depending on antenna choice (build vs. buy) and accessory quality.

Setup 2: The Optimized Performer ($1,800-2,200 Total)

For the operator who's done 20+ activations and wants faster setups, more band coverage, and better performance without going ultralight.

Radio: Icom IC-705 ($1,300)

The IC-705 is purpose-built for portable operating. 10 watts HF/VHF/UHF (all-mode), built-in battery, GPS, Bluetooth, D-STAR, WiFi, SD card recorder, waterfall display, internal ATU — it's a shack in a box that weighs 2.2 pounds with the battery installed.

The trade-off versus the G90: half the power (10W vs. 20W). In practice, this matters less than you'd think for POTA. Activators have a built-in advantage — hunters are listening for you on known frequencies, often with big antennas. I've done over 100 activations on 10 watts with no failures to get 10 contacts. On FT8, 10 watts is plenty.

Where the IC-705 shines: the waterfall display lets you see hunters calling you (crucial on a busy band), the Bluetooth pairs with a phone for spotting/logging, and VHF/UHF capability lets you activate parks using 2m FM if HF conditions are poor. The internal battery gives you about 2 hours of light operating — useful for quick activations without external power.

Antenna: Elecraft AX1 + AX2 Extender ($250) plus EFHW for 40m ($80)

A two-antenna system that covers different scenarios:

The Elecraft AX1 is a telescoping whip antenna that mounts directly on the IC-705's BNC port. It's a compromise antenna — short, lossy, narrow bandwidth — but it sets up in 30 seconds and works for quick activations in open spaces. With the AX2 extender (adds 17m and 15m), you cover 20/17/15m. For picnic table operating where you can't throw wire into trees, it's invaluable.

The EFHW for 40/20m is your primary antenna when trees are available. Same wire antenna as Setup 1 — just deployed when you have suitable supports. The IC-705's ATU handles the impedance variations across each band.

This dual-antenna approach means you always have options. Urban park with no trees? AX1 on the table. Forest park with tall pines? EFHW up high. The IC-705's BNC connector and internal ATU make switching between them trivial.

Battery: Bioenno BLF-1212A 12Ah LiFePO4 ($140)

12V, 12Ah, 3.3 pounds. With the IC-705 drawing about 2.5A on transmit at 10W, this battery provides 4-5 hours of solid operating. For most activations, you'll come home with 60-70% battery remaining. This means multi-park days (2-3 activations in a day trip) are comfortable without recharging.

Alternatively: use the IC-705's internal BP-272 battery for quick 30-minute activations and save the external battery for longer sessions.

Accessories

• Icom LC-192 backpack ($200, optional): Purpose-designed for the IC-705, with internal pockets for accessories. Nice but not essential — any padded camera bag works.
• CW paddle — American Morse Equipment Porta-Paddle ($60): If you operate CW, a lightweight paddle paired with the IC-705's internal keyer is the fastest way to make contacts in POTA. CW cuts through QRM better than SSB at low power.
• Phone with HAMRS app (free): Real-time logging with auto-fill for common fields. Much faster than paper in good weather.
• SOTAbeams 10m mast ($60): Telescoping fiberglass pole for deploying the EFHW without needing trees. Stake it with guy lines and hoist the wire along its length.

Total weight: approximately 6 pounds (IC-705 + AX1 + battery + minimal accessories) for fast activations; 10 pounds with the EFHW and mast for full-performance setups.
Total cost: $1,800-2,200 depending on accessories.

Setup 3: The QRO Trail Warrior ($2,500-3,200 Total)

Maximum performance from a backpackable station. For operators who hike to their activations and want every advantage once they arrive.

Radio: Elecraft KX2 ($900) + KXPA100 Amplifier ($900)

The KX2 alone is a 10W wonder — 160-6m, internal ATU, internal battery, CW keyer, 14 oz with battery. It's the gold standard for ultralight portable HF. But for POTA, you're usually stationary for 30-60 minutes, and an amplifier dramatically speeds up activations.

The KXPA100 adds 100 watts in a 3.5-pound package that integrates seamlessly with the KX2 via the accessory cable. Together they're a full 100W station weighing under 5 pounds. During the hike in, run the KX2 alone at 10W for summit breaks. At the park, connect the amp and run 100W for fast activations.

Why not just bring a G90 or IC-7300? Weight. The KX2+KXPA100 is 4.8 pounds combined. An IC-7300 alone is 9.3 pounds — and requires an external power supply. For drive-up activations, bring whatever. For hike-in parks where every ounce matters, this combination is unmatched.

Antenna: QRPGuys Tri-Band EFHW (40/20/10m) ($45 kit)

A linked end-fed half-wave with resonant lengths for 40, 20, and 10 meters. The links let you choose your band by connecting/disconnecting wire sections. At solar maximum (current conditions in 2024-2025), having 10 meters available is huge — the band opens with workable signals even from modest wire antennas.

The QRPGuys kit is $45 and takes an afternoon to build. Total wire weight is about 3 oz. It handles 100 watts comfortably (continuous duty on SSB is fine; long CW contest runs, add a fan to the transformer).

Alternative: LNR Precision EF-10/20/40 if you'd rather buy than build ($120). Same concept, better weatherproofing.

Battery: Dakota Lithium 10Ah LiFePO4 ($120) or Bioenno BLF-1215A 15Ah ($170)

Running 100W SSB, the KXPA100 draws 20+ amps on transmit peaks. This is where battery sizing matters critically — a 9Ah battery will sag under 20A load, potentially triggering the amp's low-voltage cutoff. The 15Ah Bioenno handles peak current without issue and provides approximately 90 minutes of 100W operating at 30% duty cycle.

For weight-conscious activators: bring the 10Ah for a single 30-45 minute activation at 100W, or use the KX2 alone at 10W for lightweight activations and save the amp/battery for drive-up parks.

Accessories

• SOTAbeams Tactical 7m mast ($50): Lighter and more packable than the 10m version. Seven meters still gets impressive performance from an EFHW.
• Elecraft KXPD2 paddle ($80): Mounts directly to the KX2 for CW operating without a separate paddle cluttering the table.
• Lightweight ground stake + bungee cord ($10): For securing the mast base in windy conditions.
• USB-C PD charger + car adapter ($30): Charge your LiFePO4 between parks during multi-park days.

Total weight (full kit): approximately 12 pounds including mast and all accessories.
Total weight (ultralight, KX2 only): approximately 4 pounds with internal battery and wire antenna.
Total cost: $2,500-3,200 depending on battery choice and accessories.

Band Strategy for POTA Activations

Regardless of which setup you choose, band selection drives success:

• Morning activations (before 10am local): Start on 40m (7.290 SSB, 7.030 CW). Early morning gray-line propagation produces pileups from stations east of you.
• Midday activations (10am-3pm local): 20m (14.290-14.340 SSB, 14.060 CW) is prime time. If conditions are good, check 15m and 10m — during Cycle 25 peak, these bands are often wide open.
• Late afternoon/evening: 20m stays open. As it starts to close, shift to 40m for the evening gray-line window heading west.
• FT8 anytime: 14.074, 7.074, 10.136 (30m, no SSB allowed). FT8 produces contacts even in poor conditions, but it's slower per contact than SSB phone with a pileup.

Pro tip: Spot yourself on POTA.app before you start calling CQ. The hunter network will find you within 2-3 minutes of being spotted. Without spotting, you might call CQ for 10 minutes before anyone finds you. This single habit is the difference between 10 contacts in 15 minutes versus 10 contacts in 45 minutes.

What NOT to Bring

Lessons learned from carrying too much gear too many times:

• Skip the laptop unless you're running FT8. A phone handles logging, spotting, and band monitoring. Save the 3+ pounds.
• Don't bring a radio you haven't operated at home. POTA is not the place to learn your new rig's menu system. Get 50+ contacts from your shack first.
• Resist the antenna analyzer. Cut your wire antenna to length at home, verify SWR at home, mark your link positions. In the field, deploy and transmit. If your setup is proven, an analyzer is dead weight.
• Skip the generator. Modern LiFePO4 batteries at 10-15Ah easily sustain a 1-2 hour activation. Generators are heavy, loud, and annoy other park visitors. If you need more power, bring a second battery — still lighter and silent.
