One-piece folding ground plane ("jungle") antenna, tuned for 70cm and GMRS. It packs smaller than most handheld whips. There's no frame to assemble, no sticks to find, and no parts to lose. Unfold it, hang it, and connect your coax.

How It Works
A ground plane (or jungle) antenna is a quarter-wave vertical with its counterpoise built in: a vertical radiator and three radials angled down from a central hub, fed through a BNC connector so your coax hangs straight down. The vertical element folds down for transport, and an isolation ring at the top, labeled with the tuned band, makes it easy to hang and identify.
To deploy: unfold the vertical element, connect your coax, and hang it.
Field Reports
Independent YouTube reviewers have tested it on both 70cm and GMRS, and one GMRS user reached a repeater about 30 miles away. Read the reviews.
Built to Last
- 6th generation of my Jungle Hub design
- I personally cut, solder, crimp, assemble, and test every antenna
- The hub is UV and impact resistant, and fully potted to seal out weather
- 14-gauge stranded copper wire with a polyethylene jacket that stands up to repeated folding without kinking
- Aluminum cable stop, so no rust
- Suitable for outdoor installation (for long-term use, seal the coax connection with Coax-Seal and secure the antenna so it can't twist in the wind)
Perfect For
GMRS users, POTA, SOTA, EmComm, search and rescue, special events, go bags, hiking, backpacking, hunting camps, apartments, HOA homes, and hotel rooms.
FAQ
What is Band Bias? I tune each antenna to favor either 70cm or GMRS. You choose which one when you order.
What does 100W+ mean? I use real antenna wire and connectors made for amateur radio. My own gear only goes to 50W, so that's the most I've tested, but I've seen nothing to suggest they can't handle much more.
Questions about which antenna fits your radio or band? Contact me. I usually reply within a few hours.
