I can normally pick up traffic 15-20 miles away as long as it’s airborne at a decent altitude, 8-10,000ft or higher and have even heard comms from a C-130 on the departure frequency at 23 miles from my location!! I can pick up the tower frequency for my local airport while I’m 1 to 1-1/2 miles away in my car. Great antenna, worth the buy if you have a handheld scanner that you use at your local municipal or international airport!

The reception seems better, with transmissions heard from aircraft near our airport, 23 miles away. For the price, I am satisfied with this antenna. **Q: Does this have a male or female bnc connector? Or in short, will it fit a Uniden BCD436HP?** A: Hello Cody, The BCD436HP has a SMA connector so the RH77CA would not work with the unit. The SRH77CA will fit the BCD436HP.Thank You! **Q: Are any adapters or additional equipment necessary to use on a uniden bc75xlt in place of the stock antenna? sorry i am a beginner. thx.** A: The Diamond RH77CA is the best replacement antenna available for the BC75XLT. It has a male BNC type connector, which matches your scanner. No adapter needed. **Q: I have a bc125at scanner and bought this antenna. i don't see how it will fit because it has a female connector. scanner has a two pin twist on. help.** A: This antenna should work just fine. The inside of the antenna has two notches on the edge, line those up with the notches on the scanner and twist it on. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing Range *by A***X on October 30, 2024* Bought this antenna for my Uniden BC125AT after reading reviews of other buyers recommending to replace the antenna that comes with the scanner.
