CA-2X4SRNMO Comet CA-2X4SRNMO Mobile VHF/UHF Vertical Antenna

I bought this antenna primarily to use on my boat where I wanted to shared an antenna feed with both a GMRS radio, and a Marine VHF radio using a frequency-split diplexer. In that application it works great. Signal strength is very good, SWR at those frequencies is very good (<1.3:1) and installation was exactly how I expected.But then I discovered that this is also just a great all around antenna for 2m, 70cm, MURS, GMRS, Marine VHF, and in scanning (receive only) applications from 25MHz to 1.3GHz. I have one hooked up to my RTL-SDR, for example, so I can scan any service within its bandwidth range.The fold-down is rather stiff. I don't use this in offroad conditions currently, so I don't need a spring. But a spring kit is available if you need it to be better protected offroad. It's a rather long antenna due to its compatibility with 2m VHF. But it's a good all around antenna, very effective at the ranges I've tested. Recently I used it to hit a GMRS repeater 64 miles away with a 4w handheld.

I use this on my Anytone 578UViii Plus mobile in my truck with a midland mag mount. Works on 2M, 1.25M, 70cm, MURS, GMRS, and DMR. All SWR readings are low to mid 1's except GMRS coming in at 1.98 which is still acceptable for my setup. Range is excellent. TX and RX has increased significantly for both Amateur and GMRS. Don't hesitate to order this.

The best I’ve used for 2M, 70cm. The gain over the cheap magnetic antennas I’ve tried is like night and day. Very clear. Would highly recommend.

This antenna unlike another oneni bought before this one works GREAT!! Very low SWR out of the box, unlike the HH9900 I bought that was showing an SWR of 6 or higher. Will buy another one of these.

Really excellent antenna....fully tested and tests well beyond expectations. The only thing bad about it is it tastes weird but other than that it's excellent.

Set for the frequency I use the antenna for, went to the radio and got a 1.1:1 match for swt. Range is great with 50w radio. Using this for GRMS frequency.

Almost 1:1 across 2m, 70cm AND 220 band!!! Works great on GMRS & MURS too, almost 1:1! This is one of the BEST VHF-UHF antennas I have ever owned! (And I have a lot of antennas!)

This fell apart twice after being mounted. The first time I was lucky enough to find the top half. The second time I had put loctite on all the (many) screws and the top half STILL fell off. It's very stiff and I worried it would break or bend if I hit anything like a tree branch. Now I need to buy another antenna.
