RV rental for ARRL Field Day — June emergency-comms remote operating

ARRL Field Day, held on the fourth full weekend in June, is the most popular amateur radio operating event in North America and the closest the hobby gets to a national emergency-comms drill. Tens of thousands of operators set up portable stations in fields, parks, and dispersed BLM sites and operate 24 hours on emergency power. For ham operators with an RV, Field Day is a natural deployment — the rig is the shack, the battery bank is the power supply, and BLM dispersed camping near a clear horizon gives a strong antenna environment. This page surfaces the planning math: power budget, antenna deployment, dispersed camping rules, and how amateur radio operators can find a Field Day-friendly rig on the PickRV marketplace.

Field Day rules + emergency-power bonus. ARRL publishes the Field Day rules annually on the ARRL Field Day page — the operating categories (1A through 1H plus the various class modifiers), the QSO point values per band/mode, and the bonus point structure for emergency power, alternate power (solar), public locations, message handling, and youth participation. Pure emergency power — battery and/or solar with no generator and no commercial mains — is the cleanest bonus path for an RV setup and is one of the easier multipliers to claim. Running off the engine alternator with the engine running does not count as emergency power per ARRL rules. Verify the current year's rules before the event.

Power budget per radio. A typical 100W HF transceiver in SSB voice mode draws roughly 20-25A on transmit and 1.5-2A on receive. Over a 24-hour Field Day at a moderate 30% transmit duty cycle, that's roughly 200-250Ah of draw. A 100Ah lithium house battery in a Class B van is enough for one radio + casual operating with a 200W solar panel topping up during the day. A 300-400Ah lithium bank in a Class C with 400W solar comfortably runs two simultaneous radios plus a 500W amplifier for the full 24 hours. CW (Morse code) and digital modes (FT8, RTTY) draw significantly less than voice — a CW-only operator can run 24 hours on a much smaller battery. Plan the power budget per radio per mode per duty cycle.

Antenna deployment from the RV. The most common Field Day RV antenna is a portable HF dipole supported by a 25 to 30 foot fiberglass mast lashed to the rear roof ladder or guyed off the rig with stakes. A vertical antenna with 4-8 radial counterpoise wires also works well. Keep all antenna elements clear of the rig roof, AC unit, satellite dome, and any 12V wiring to avoid RF feedback into the rig electronics. Most PickRV hosts will not allow permanent antenna installations (no drilled holes, no through-roof mounts) — plan a non-invasive temporary deployment that takes down at the end of the weekend with no trace. Always confirm the antenna plan with the host before driving the rig off the lot.

BLM dispersed camping for Field Day. BLM-managed dispersed camping is the dominant Field Day choice because it offers wide open land for antenna spread, low RF noise floor (no overhead power lines, no industrial RF sources), and the 14-day stay limit covers the weekend easily. For the June Field Day event, mid-elevation BLM in Colorado, Wyoming, Utah, and northern Arizona stays comfortable. The Quartzsite AZ area is too hot in June (110°F+) — Quartzsite is a winter Field Day option. Verify the current BLM dispersed camping rules, road closures, and fire restrictions on the local BLM Field Office page before driving in. Pack out everything you bring in.

Finding a Field Day rig on PickRV. PickRV is a multi-vendor RV marketplace; inventory grows as more owners list their rigs. Ham operators planning Field Day should search the relevant state (Colorado, Utah, Wyoming, New Mexico, or Arizona depending on the planned deployment), filter for your dates, and message hosts directly about your Field Day weekend. PickRV does not currently supply ham radio gear, antennas, or batteries as rig add-ons — operators bring their own. Confirm any antenna-deployment expectations with the host in writing before pickup.

When is ARRL Field Day each year?

ARRL Field Day is held annually on the fourth full weekend in June, beginning at 1800 UTC on Saturday and running 24 hours. It is the largest emergency-comms preparedness event in North America and the most popular operating event in US amateur radio. Field Day rules — including emergency power requirements, operating categories (1A through 1H), and bonus point structure — are published annually on the ARRL Field Day page; confirm the current rules each year before deploying.

What's the power-budget difference between Class B van and Class C for Field Day?

A small Class B van with a single 100Ah lithium house battery and a 200W solar panel will sustain a single-radio 100W HF station for 24 hours of casual operating with margin, but will struggle with two simultaneous stations or any heavy SSB voice operating. A Class C with a 300-400Ah battery bank and 400W solar can comfortably run two radios + amplifier for the full 24 hours. Pure emergency-power operating (no generator) earns ARRL bonus points; running off the engine alternator does not count as emergency power. Plan your power budget per radio + duty cycle.

Can I use the RV's roof for a temporary antenna?

Yes, with caution. A small portable HF dipole supported by a 25-30 foot fiberglass mast lashed to the roof ladder is the most common Field Day antenna in an RV setup. A vertical antenna with an elevated counterpoise also works. Keep all antenna elements clear of the rig roof, AC unit, satellite dome, and any 12V wiring. Most PickRV hosts will not allow permanent antenna installations (drilled holes, through-roof mounts), so plan a non-invasive temporary deployment that takes down at the end of the weekend. Always confirm with the host before mounting anything to the rig.

Where do RV-mounted Field Day operators typically camp?

BLM-managed dispersed camping is the dominant choice because it offers wide open land for antenna deployment, low RF noise floor, and the 14-day stay limit easily covers the weekend. The Quartzsite AZ area, the high desert of NV, and the eastern slope of the Sierra are popular winter-to-spring Field Day sites; mid-elevation BLM in CO, WY, and UT work for the June event itself. Verify current BLM dispersed camping rules and seasonal closures on the local BLM Field Office page before driving in.
