FSR vs CB?

About 60% of our active off roading members have CB's but the last trip we ran into communication issues with our CB's since we got a little more spread out than normal. Would using FRS's be a better way to go?

In my experience, reception with hand held FRS/GMRS is comparable to a mobile CB. And in some instances have worse reception than CB, due to the short little antenna on the FRS/GMRS hand held, especially if the hand held is used while inside the Jeep Vs. a properly installed externally mounted (and longer, even if only @ 2'-3') CB antenna.

IME; YMMV, and invariably will...

I'm more inclined to think some of the CB antenna installs weren't done properly and/or properly tuned for a good low SWR for maximum range. I occasionally lead very large groups that can get spread out in deep desert canyons with no CB communication difficulties between the front and rear jeeps.

In fact HF CB transmissions are less likely to be affected by difficult mountainous terrain than line-of-sight VHF/UHF ham radios if no repeaters are in the area.

As a General Class (N6TAY) ham I'm not against ham radio, I'm just being practical here.

It's easy to have a bad antenna on your Jeep. And the antenna is 10x more important than the radio that drives it. Even a good antenna that's not tuned properly won't work for spit. On the other hand, a really good antenna that's tuned well will make the cheapest radio sound great.

Getting your antenna tuned is always a good idea. You can do it yourself if you want. It's not all that difficult to do. Just get an SWR meter and watch a couple of youtube videos. In a couple of hours you can get it working.

It's also a good idea to give your antenna a checkup once a year. It can drift out of tune over time.
