A modular ground plane that threads directly onto your SMA antenna using custom attachment nuts, machined in the USA and silver plated.
Why it matters
Most small radios use monopoles without a real ground plane, so your “ground” becomes whatever it can find — PCB, battery, your hand…
That leads to inconsistent performance.
A proper ground plane fixes that.
What you get
Note: Needs some clearance around the antenna. Not sure if it’ll fit your setup? Just ask
New Antenna Upgrade Available!
If you’re running a monopole, this is one of the easiest ways to get more signal and way more consistency.
The Delta Plus Proto Modular Ground Plane threads directly onto your antenna using our custom attachment nuts — machined in the USA and silver plated.
No inline adapters, no extra loss.
What we’re seeing:
All data shown is from real trace route testing with a Muzi Works whip, using a ground plane on one radio.
Run it on both ends and you can expect even more improvement.
Use the 203mm for max performance if you can handle it!
