Radtel Aviation Antenna 108-136Mhz, 14.96 Inch Walkie Talkie SMA-Female Air Band Antenna Compatible with Baofeng 5RM Radtel RT-890 RT-470X RT-730 RT-900 RT-4D UV-K5 K6 TD-H3 TH-H8

I have a TalkPod A36 Pro Intl version and I have this mostly for the ability to listen to planes in the local area and occasionally listen to the locals on repeaters. This antenna even though tuned for Aviation Bands 108-136mhz which it still allows better than stock antenna's reception on the higher bands. When it comes to aviation bands on my A36 it is definitely a vast improvement over the stock antenna for sure. It is much longer but is very flexible and can bent down to fit in a case or removed easily. This antenna gets plans communicating with ATC at a distance maximum in my area of over 80 miles away. I cant hear the local airports tower (rarely at night inside) but if I go outside the airport is about 6 miles away and I can make out the ATIS as well as the tower and departure and clearance delivery channels without issue. The old antenna could never hear the tower or ATIS so there is a vast improvement with this antenna. Great Buy fast Shipping and Works great you cant go wrong! NOT just for RADTEL Radios at all. Fits most handheld.

Although I wasn't necessarily a fan of these modern "tactical" (?) antennas that fold, it seemed like it was going to be better than the original antenna that came on my Radtel RT-490. I was not really impressed with it's receive or transmit and had hoped this might make a difference.Well, I'm impressed. After installing, I noticed immediate improvement in receive. Transmit seems much better although I haven't had any QSOs using this antenna just yet. But I gotta say the receive is so much better, even on air band. The ability to fold it is nice since it is long; you can still receive when folded but performance is much better unfolded. I strapped the included velcro to the antenna unfolded, so that it will always be there when I do want to fold it.

Increasing the input of frequency and out put.

Nice but wish they made it with BNC connector. Apparently it is very hard to find an Aviation Band antenna with BNC connector for Icom radios. Tested radio out and it seemed to get good reception.

Arrived in time and undamaged. Fits just fine too. It comes with a rubber grommet so be careful you don't lose it during opening the package. Receives well on AIRCRAFT bands.

The antenna works. It is competitively priced. It is a 13” antenna. And it arrived in a 4 1/2” package. It is not vertical as shown in all the photos. It looks like a bent carrot. See it compared to a similar antenna (left) properly packaged and shipped.

Better gain than the stock antenna

Doesn't work any better than stock antenna. I tried using this on a Baofeng BF-F8HP Pro. Yes, it could be a problem with overload or spurious emissions common to Baofeng units, but bottom line it didn't work any better than stock; stock was able to pick up several channels that it couldn't, and the signal was stronger on those that both picked up. I wasn't even using the dedicated stock airband antenna which will likely be superior to both. Tried it with and without rubber gasket. The gasket is also too big and I had to cut it down. Overall, a waste.
