This antenna upgrade is perfect for extending the range of your LRS/UHF system.
About this Product
This antenna upgrade is perfect for extending the range of your LRS/UHF system.
The Moxon rectangle is essentially a 2 element Yagi with the elements bent to direct the signal forward. The advantages of this antenna is the very high F/B ratio of about 25. Unlike the Yagi which has deep nulls to the sides, the Rectangle has it's nulls to the rear. This makes for an excellent LRS/UHF FPV antenna.
It has a good frontal sweep of nearly 180 degrees and allows you to fly to the sides of the antenna without excessive degradation of signal. Do not fly behind yourself with this antenna. Gain is 5.75 dbi. Range boost is ~70%.

Good Antenna
Nick
Don't have an SWR meter but with testing today, I saw a dramatic increase in performance over the Omni whips I was using as far as the RSSI was concerned. I am using as my Ground Station Antenna for Ardupilot telemetry.
Poor construction!

As the other person wrote. White tube cracked during first use. Was going to return it but ended up patching it myself.....
433 Moxon antenna
Dennis T.Verified buyer
I could not believe how poorly this antenna was made, wire was bend off the supporting plastic, the side gaps had different gaps ( and they are important to be the same and correct values). At the end, I built my own Moxon antenna and it outperforms this commercial one by 3dBm consistently
Great range but poor construction

Let me start by saying that I own two of these antennas. I have achieved 7.5 mile range with RSSI to spare on OpenLRS TX/RX. The weak antenna support is what I hate about this antenna. Both of my antennas have broken near the base of the white plastic support tube that the coax runs though. Even before they broken the support is very flimsy. As much work as IBC has put into tuning the antennas you would think he would have built them to last. I reinforced mine with a wooden dowel and zip ties.
Good antenna if needed

I wasn't getting good range with my Vortex using the 4 ch IRC rx with sander ant and SR771 on tx. Went to this ant for the tx and it was resolved. Still not as good as using the IRC diversity rx and two sander ant's but good enough for quad use.
