[Elecraft] Remoting a KAT500

[Bill Phillips]

I completed a remote KAT500 installation this summer and have been using 
it successfully ever since.  In my case I use the KAT500 to switch among 
3 "Lazy H" antennas pointing more or less 60 degrees apart. I use the 
utility program to do the switching and to monitor SWR. The KAT500 is 
capable of being pre-tuned in 20 KHz segments for each of the antennas, 
but you need to run 20-30 watts to accomplish this. Thereafter a 5 watt 
qrp ditditdit will switch the tuner to the memorized tuning for that 
frequency and antenna.
I used 150 feet of direct bury CAT5 cable for the serial connection 
between the computer and tuner. One twisted pair for Rx, one for Tx, and 
two for the PA key line.  It works just fine.
I hope to get some pictures up before too long.  In the meantime let me 
know if there are more questions.
By the way I got a lot of help and good ideas from Knut AB2TC and David 
at Elecraft.

This topic may have been covered before, but I can't find it specifically in
the archives.  I am thinking of remoting my KAT500 ATU and using it at the
base of a non-resonant vertical.  My ideal is to install the tuner in a NEMA
raintight box and powering with dc sent down the coax with bias-T's at both
ends.  I will have to rely on RF sensing since it would impractical to use
control cables for the 60 ft run.
  
Any thoughts?
