    They were available in abundance when I was in Singapore last year, as cheap as $150 for 80w amp.

    Know any? PM me.

    Leglalities aside, its possible to to add an "afterburner" betwen your radio antenna port and aerial, that would up your transmit power, but how you gonna switch it out on receive mode ?

    Bingo!!!

    Not only are they illegal, they're a waste of freakin time and money!

    Man, I lived in the 27meg / UHF heyday...

    We ran 1000w linears on the 27meg sets and blew the people away (ever seen a 9 foot stainless glowing? we have) ran receive amplifiers, co-phased antennas...

    Heck, we even mounted a home base 27 mhz antenna AND a 12 element UHF beam (with rotator) to a vehicle (and used it!!!!)

    Been there, done that, its boring and pointless....

    Theres no point using one, why shout to someone when they can only whisper back? Defies the point of 2 way communication.

    Maximum legal power on UHF CB is 5w. Since UHF propagates almost completely line of sight, increasing power merely allows you to shout over the top of other users, which won't win you any friends. I have found that range is almost the same using a handheld on 500mW as with a vehicle mounted set on 5w. Main thing that matters is the height of the aerial - where I am (base antenna about 10m above ground) it is nearly impossible to get someone 2km away on the other side of the hill, but no problems with another base station with a high antenna on top of a mountain 100km away.

    No, I don't know where you would get a linear amplifier.
