Hi, I'm not a ham-radio guy, but I know you all know your stuff and might be
able to help me out.

Presently I have a transmitter (in a truck) and receiver (Water pump system)
set up I use to irrigate a motocross track. The signal is transmitted
1/2mile, parallel to high voltage lines. Frequency is at 27.145MHz and at 1
Watt. Unfortunately the signal reception is intermittant - I'm assuming
because of the EMF of the high voltage lines. I have both a really good
antenna for the reciever and transmitter.

I need a CB amplifier for the transmitter. Perhaps 3 Watts? Preferable w/ a
BNC connector and runs off 12Volts. Does anyone know where I can get such a
device?


if your cb isn't putting out even 3 watt it is defective

spend 49 buck on a new cb

your operation will be legal and likely cheaper than any amp you could
build

Just because his Xmitter is only 1 watt doesn't mean there's anything
wrong with it. Something you probably don't know and didn't bother to
lookup is that 27.145 is a remote control frequency and NOT a voice
frequency. Many RC controllers put out less than the voice CBs you're
thinking of.

It's still illegal to put an external amplifier on the unit, even if the
total output power doesn't exceed the maximum allowed for the band.

It is funny how people with problems like this always look to boost
transmitter power, which as noted is not legal, and never consider
improving the receiver end, which is both legal and more likely to
work.
Happy trails,
