I purchased these hoping the signal would be better than the $8.00 antennas HK also sells. Using a 5.8ghz immersion 600mW transmitter the second my quad turned to face me, around 20ft away from where I was sitting, my the signal almost completely cut out. The cheaper antennas held better signal strength than these at farther distances.
Based off of what I've seen, you'd have a better flying experience going with Aomways.Very good antenna. Used it in my immersionrc vortex and dominatorhd googles. Compared to ib crazy and fat shark spironets I could not tell the difference so I use these with confidence in my mini quads. The white top did come off in a high speed crash but since then put CA glue so it will no longer come off. Don't see a need to open the antenna anyways. The wire is thick and stays in place just like the fat shark.Great antennas. Well put together and the cables stay when bent. Verified RHCP and tested. Work great and have increased my range by about a third over stubby antennas available here. This will be my goto CP antenna set.
