[Elecraft] KX3 remote transmitting

[Wes]

1100 feet of 7/8" Heliax would have about 2dB loss at 30 MHz.   That's the $7000 solution. But it works well on receive too. :-)

Something like LMR-400 will cost about $1100 and have about 7dB loss. A KPA-500 has about that much gain.  I would keep it in the shack. That's the $3200 solution. 

Either way you still have a 10 Watt radio.

 Another consideration would be to look for some surplus 7/8" CATV cable. In years gone by, I've been given the stuff as it was being removed from power poles.  That could be a near zero cost option. 

Last you could try remotely controlling the radio.
