This is a hypothetical question. On a system that has a cb radio and an antenna tuned to 1.2 vrs 1.3 channels 1 and 40, when you add a cheap 150 watt linear amp and the swr goes stupid high, where would you install a 30 mhz low pass filter and where would you measure swr after installing the filter???
After my 2001 Superduty F350 was stolen, I replaced it with a 2019 Jeep Wrangler 2 door. I never realized how problematic mounting antennas for GMRS & CB was.
50 watt GMRS and a CB (with a little extra).
Suggestions with pictures would be appreciated.
Hi, the GMRS V-1 radio was originally sold as a 5 watt radio. I have 2, and they put out a measured 3.7 and 3.4 watts. I'm not sure why but they (Btech) changed their adversing to 2 watts. I suspect they were advised by the FCC to change their radios.
Consider this comment as food for thought. I've noticed some interest in HT radios with higher tx wattage. As these are held occasionally as a phone, against one's head, how desirable is a 10 watt HT? Even held 6 to 8 inches from your mouth is 10 watts safe?
Changing GMRS from wide to narrow band would be an easy way to get rid of GMRS completely. The elimination of wide band radios and repeaters would leave most serious GMRS users discouraged with the thought of replacing their equipment. The FCC could use the argument that as both FRS & GMRS share frequencies they should both use the same band width. The reduction in usage would justify eliminating both radio services. Just saying.

The better midland FRS (used to be GMRS) are a decent 2 watt narrow band ht. I doubt a 5 watt (putting out an actual 3.8 to 4 watts) GMRS HT will perform much better without a significant antenna change. Present the radios as a communication device. If the kids think they are toys, thats all they will ever be. Adding a family licence package down the road along with a base station would still be an option. Keith T
Hi, Keith here. Im in Washougal Wa. Just East across the river from Portland Or . The good side of the river. You will do best if you can mount your antenna in the center of a 61/2 in of metal that is well grounded
Hi, Im using 2" pvc pipe mounted on a pivot mount on my hunting trailer (16 x 7 ) enclosed cargo trailer. This pipe is 20 ft long. A 10 ft piece of 11/2 in.pipe extends this mast to 30 ft above ground. One of these for a gmrs repeater and one for CB. On opposite corners of the trailer.
Hi, I live in SW Washington state, just accross the river and a little east of Portland OR. Almost all gmrs traffic I hear is simplex and mainly construction companies for traffic control. There is one factory on ch 18, also simplex. The only other usage is during hunting season. Beside mine (mobile) there are several repeaters poping up but well inside the national forest, Pinchot Gifford.
In the case of someone that either has no fcc license, or at most, a license that you get for a $70 check (no testing) a CB has better range, especially in the hills. It is also cheaper, but no CB fits in your pocket. In a vehicle, both are good.
Hi David. Welcome to this forum. I understand your distaste for CB radio. Unfortunately CB frequencies are better than ANY UHF frequencies. Especially for family comuications. The FCC has completly ignored their responsibilities in enforcing their own laws.
