TWAYRDIO RH770 SMA-Female Telescopic Handheld Ham Radio Antenna 2m 70cm VHF UHF Replacement Extendable Antenna High Gain fit Kenwood TK-360 TK-370 TK-3200 Walkie Talkie

I have been using this antenna on my HT for at least five years now, so I feel I can give a valuable review. I would recommend this to anyone. The build quality is great - this is not flimsy junk. It greatly improves signal quality, especially outdoors. I highly recommend it.

Great antenna! Made a big difference on receive and transmit for 2m. When extended its a long one.

Great fit

Didn’t work so well with my GMRS radio but works fine with my other HT’s

I tested this antenna hoping to find a good retractable for hiking and SOTA activations to go on my Baofeng handhelds. It measured 1.05 SWR on an antenna analyzer, and 1.2 on my VNA around 146 MHz. However, despite over an hour of experiments with the VNA and analyzer at different lengths of this antenna I failed to find any place on 70 cm where the SWR was below 2.6.Since I have a similar antenna for my Yaesu FT-817, I hooked it up and while it wasn't as nice on 2 M (1.3) is was under 1.5 for 70 cm, so I elected to return the RH 770 and continue looking.

The antenna came earlier than expected. I tested it on a NanoVNA and it has great SWR on the frequencies I use in the 2m, 70cm, and GRMS bands. Only downside is that the antenna has a little bit of wobble extended or not. Hoping it doesn’t get worse over time.

This thing is heavy! I knew it would be, just not how much. It puts considerable strain on the connector. I have decide to use this for very specific applications and not for everyday use. I used it for a couple of events and not sure I could tell a difference from my Nagoya 771.

Works very well, for 2m -70cm , also the receiver is fantastic!! Great size Antenna, For Good coverage!
