The KW-7 is the best out there (to me). I'm running a PRESIDENT LINCOLN II V-3 radio and my SWRs are 1.4 at 28.700 and 1.3 at 25.700, all cb channels are 1.0. Can't go wrong buying a few of them. Plus CB WORLD has the cheapest price that I've seen.
KW7 is the BEST of the best. I have tried KW5, KW6 and Wilson antennas, none even come close to the KW7. I'm running a PRESIDENT LINCOLN II V-3 and the SWRs from 28.600 to 25.600 are at the highest is 1.3. From about 27.900 to 26.100, the SWRs are 1.0. No other antenna that I know of can do this in a car.
Bought 2 Green 7 ft. FireStik's and they look great on my truck! Couldn't be any happier!
These antenna's were ordered for my son, they arrived very quickly, he was thrilled to see them and they were mounted the day he got them. They are awesome. Thank you all so much !!!
Very good reception could here my friend for a couple miles through town! Suggest heAvy duty mounts these antennas are very heavy
Recieved my whips in just a few days with the cheap shipping, they're a great product for your truck or whatever you got. I'm very pleased with the reception they pick up and would highly recommend them.
Still considered an old school antenna made right in the USA. I got my 7' KW7-R in Maine very quickly. Great addition to my antenna collection. Recieves and transmits, A-1! First day, talked to at least 6 stations on 27.285 MHz around the gulf coast states. Got good responses. Keeps a good posture at highway speeds. Antenna is on a custom mount near the bed on my truck, Bulldog 777.
Nice quality antenna. If you want one of the best performing antennas out there, the 7 ft. Firestik won't let you down. Install this antenna properly and you will have an impressive performing mobile station.
