I've had this exact antenna on my car in operation for about almost 8 and 1/2 years now.. works well with my gmrs radios as well as my ham radios.. I found that this antenna does very well simplex when in the Hills where I live here in Washington State.. the only thing that I've had to keep an eye on is the insulators starting to fade in color and look a little bit old because of the UV... but it's still going and I'm happy about that.. hope I get another eight years😎✌️

Great antenna, I've had mine mounted to a pedistal NMO mount on my tool box in the bed of my truck for 7 years now. I've hit every bank teller drive through and fast food low access bar and it has been the strongest antenna I've seen with mobile use. Great video...73 N7EWC

Great review thanks and swung my wallet! I'm going to be using it at home outside my shack and also portable on the road with IC-705. Great you shared the SWR tests. Take it easy and 73's from Amsterdam.

thanks for the video. I had a small version of that antenna and was well satisfied with it until it got removed from my truck without my permission. My next purchase will be that antenna because I didn't know that had that version.

Just purchased a CA-2X4SR! It sits on top of the cab of my Tacoma. Out of the package it ran an SWR of 1.1 at 146.520! Made the 1st contact with it over 50 miles away. I am very happy! I will be looking for the spring upgrade.

Appreciate the video review. This is the antenna I'm going to use for my mobile install on my Tacoma. Instead of vaseline though, I plan on using Noalox by Ideal to coat the antenna base threads. 73 de K4WSD

No Vaseline, petroleum will corrode rubber (Seals). You should use silicone based product. Or you can use an aluminum based anti seize.

What’s the measurement from the top of the roof to the top of the fold in the antenna? If I magnet mount on my pickup roof I don’t think I will get in my garage.

Try testing the swr by moving mag mount in different locations on roof. On my work car Ford Taurus I have same mag mount for my dual band radio and the right rear of roof gave me the lowest swrs with better Rx and tx

Sir, Thoughts on a Yaesu FTM-400XD, Comet CA-2x4SR and Nagoya RB-700N set up? I am strongly considering the 700N over the RB-50. Thank you.

@luiz79 - All good components. Be sure to get the NMO model for the antenna mount. These components work well for me for the past year, other than the mount you suggested. I use a magnetic mount. Thanks for watching!

I bought one, I hear weather band better .But I use simplex to test it out and my old antenna had better ears. Now on 2 meter grate swr and 48 to 51 ohms and full output 50 watts of power. But now on 70cm at as good. I only get about 3/4 of power output , 35 watts of power and not 50 watts and swr is good and the radio don't like it as much as 2 meter side. So it is better than hustler mx-270 on 2 meter on swr and ohms but no as good on the ears as the hustler was. I just wish the 70cm was better on power and the ears like hustler was. But 2x4sr is better built as far I think. Diamond Sg7500 is next to test . you can't test a antenna using a repeaters, test the antenna using simplex with the same mount and location and the same person and same time. Because conditions can change . 73s and have fun

@bryanmanx 3 жыл бұрын

I have one of these and swr is worse than I've ever seen. I am using a mirror mount so there is no ground plane. Q and a on Amazon said no ground plane needed but I am wondering if that is the truth.

@brucekempf4648 3 жыл бұрын

All antennas require some kind of ground plane. Some are built into the antenna design but these vertical antennas need to be mounted onto steel like the roof to perform properly.

@bryanmanx 3 жыл бұрын

Would the lack of a ground plane affect swr?

@BrianH2288 3 жыл бұрын

Not so good here, it is resonant at 157mhz 50 ohms. @ 144 -148 it is 1.7 to 1at 30 ohms it would need lengthened but with the mid coils the lengthening would be difficult.. I am going to add the spring so i can lengthen the antenna and bring 2 meters into resonance hope 440 stays good
