Pollux Field Systems Micro-J
A small antenna with a practical place in your kit.
PREORDER — Estimated shipping begins November 30, 2026. Payment is collected when you place your order.
The PFS Micro-J gives you a deployable VHF/UHF antenna in a compact, lightweight package. It rolls into roughly a 4–6-inch coil, stores in the included 6 × 6-inch plastic bag, and weighs less than 4 ounces, including its attached coax lead.
Keep it in your radio bag, hiking pack, vehicle kit, or emergency supplies. It’s an easy way to carry another antenna option without giving up much space.
Easy to pack. Useful to have.
The Micro-J unrolls for vertical deployment, with an attached 8-foot RG174 coax lead and BNC male connector. Hang it in a suitable location, connect it to your radio, and position it as clear of nearby obstructions as practical. Some radios require an adapter, sold separately.
It’s a practical choice for temporary setups, travel, and backup use—or simply for keeping a deployable antenna with the radio you already carry.
What to expect:
The Micro-J offers flexibility in antenna placement. Hanging it higher or in a clearer location can help compared with an antenna held close to your body or surrounded by obstructions.
Actual results depend on terrain, antenna height, nearby objects, operating frequency, feedline losses, and the station you’re communicating with. No particular range or improvement is guaranteed.
Its appeal is straightforward: compact storage, low weight, and another useful option for your communications kit.
