Great antenna Time Owned: 0 to 3 months.
I too bought this antenna based on the reviews from here and to install on my F-150 with a fender L bracket. I've used Larsen, Diamond and a couple of other Comet antennas; but I never seemed to get a decent compromise with a wide enough band coverage and an acceptable VSWR. Well that was till I received my Comet CA2X4SR, I immediately hooked it up to the analyzer and the VSWR was good all across the amateur bands both 2 meters and 70 cm and it was even good all the way down to 140 MHz, but started to drop off about 160 MHz. On 70 cm it was a bit on the high side by the time I went up to 460 and this is a bit of a concern, but something I can live with. Just the same I will run the antenna as it doesn't seem to affect the performance in the amateur 70 cm band at all. In fact it out preforms my old Larsen and an old Sinclair dual band. So far I'm impressed with it and will see how it weathers the winter.

I went and got this antenna after reading the reviews here, 1st I put on my 96 jeep with a IC-2820H , it worked good. But then I put it on my 96 KW T-800 with my ID-880H. WOW

I use UHF most of the time, and all I can say this antenna beats out the Diamond Antenna NR770HB hands down! It performs and brings in repeaters that were otherwise out of range , and gets into to repeaters I couldn't even hit before.

I use it on Vhf TX on Ham, MURS,and listen to the public safety and railroad frequencies. Uhf TX on Ham, GMRS, FRS, and listen to public safety .
I think I'm go to try it on 222Mhz when my TYT TH-9000 get in.

Thanks to E-Ham and all the hams that make this site so GREAT!!

Great antenna! Time Owned: 0 to 3 months.
Great replacement for my previous Larson NMO2/70B antenna. I can hear distant repeaters better than before, and although I haven't measured the SWR, my IC-2720H shows it can put full power into the antenna without backing off for SWR protection. Very solid antenna, doesn't bend in the wind very much. It screwed right on my Larson trunk-lid edge mount, but on the hood of my truck. I'm happy with it!

Very happy with performance Time Owned: 0 to 3 months.
I installed it to the side of my truck box on my F350. Works better than expected. Well made, durable, and about 1.3 swrs. I can hit distant repeaters no problem and the simplex distance exceeded my expectations. Thumbs up!

Great antenna But!! Time Owned: 0 to 3 months.
I just installed this antenna on my Mitsubishi Lancer. Using a new Ft-2900 this is the flattest SWR/Bandwidth antenna I have ever measured on 2 meters. So why only 3 stars? The weight. When used on smaller new cars with thinner sheet metal roofs this antenna is way too heavy. It's very stiff and distorts my roof quite a bit when I press in the whip. I'm also concerened about the large open coil in the middle. It would be very easy for a small branch to becomes stuck. Don't get me wrong there is nothing wrong with the electrical performance it received and transmits very well. However I'm returning the antenna and going to a Larsen 2/70B that has a coil closer to the base and a much thinner whip.

None Better Time Owned: more than 12 months.
Excellent antenna. Does exactly as it should. 5w is all I need to work nearly all the repeaters in our metro area. Glad it was recommended by my local radio shop as one of the best.

The review about RFI....that has nothing to do with the antenna. It has everything to do with the installation and reflected rf.

A good one! Time Owned: 0 to 3 months.
I have this antenna (in black of course) mounted on a stainless steel mirror style bracket on the side of my bed mounted toolbox.

It handles tree limbs etc very well and provides excellent service. The SWR across the public safety and LMR bands is very good. I have a duplexer installed to interface between two high power Motorola Spectras (VHF & UHF). It handles the power really well, and both radios work fine together.

EXCELLENT antenna ! ! ! Time Owned: 0 to 3 months.
This antenna ROCKS! I have been busy trimming others to get a minimum SWR compromise from the HAM, MURS, and GMRS bands . . . TRIM NO MORE, this is the antenna solution for that dilemma, straight out of the bag. I would honestly say you will get SOLID (<1.7:1 SWR) 2m and MURS performance, and EXCELLENT (<1.4:1 SWR) UHF sensitivity for 440 HAM (70cm) and GMRS (64cm) bands. Most 'bang' for your buck, for those not wanting to have duplexers/triplexers and multiple sticks on your mobile. Give it a shot, you WON'T be disappointed!

Fantastic Antenna Time Owned: 3 to 6 months.
I started out with a Comet SB-5. It was mounted to a NMO mount directly secured to the middle of the roof of my Chevy 1500 Blazer.
It was a good antenna, but there is a local group who are very active with GMRS in the area so I bought a 25 watt radio for GMRS and got my license.
Using the CA-2X4SR made a very noticable difference on not only the GMRS band, but also on 2M and 440 bands.
It transmits like an antenna with far more gain than it is rated at.
It is stiff enough not to get pickett fencing at regular highway speeds and has a fold over feature when going through low hanging trees.
I give it a solid 5, the antenna is very broudbanded with low SWR across all bands.
This is a great antenna, buy one and don't back.
If you just work one band and want an antenna with more gain, there may be better choices, but for a broad band antenna, this antenna cannot be beat. Be sure to mount it with the 3/4" hole and a NMO mount for the best ground, it does need a good solid ground to be at it's best.
I have got nothing but great reports with this antenna, it's worth every die charged.

Excellent dual band ++antenna Time Owned: 3 to 6 months.
I bought the mag mount version (CA-2X4SR-NMO)from now priced at 56.75 plus shipping. It does not come with a Mag mount base and cable but you probably already have one from a not so good antenna. Excellent SWR out to 158 MHZ. The 440 ham band also excellent. No tuning needed. Near perfect out of the box. Highly recommended.
