[Elecraft] Remoting KAT500 to base of antenna

[Fred Jensen]

I'm sending this to the list, many often ask that discussions that might 
apply to others *not* be taken off-line.

After 38 years on a 5 acre "farm" in Auburn CA, we moved last fall. 
This spring I will install a flag pole vertical in the backyard of our 
new [to us] home in Sparks NV.  I will also have an end-fed wire along 
the fence, commencing adjacent to the flag pole.  I want to remote my 
KAT500 at the base of the flag pole, and use it as both a auto-tuner and 
a remote antenna switch between the two antennas.  My HOA will be happy, 
I'll be able to make some RF and see my P3 at home, and I also can run 
remote to W7RN where the coefficient of aerial aluminum is very high.

I know that the KAT500 won't likely directly match the end-fed wire, I 
know how to deal with that, and I know that no "antenna tuner" has ever 
actually "tuned" an antenna. :-)

I will have about 120' of 2 1/2" PVC buried from the shack to the pole 
and will have room in it for power, coax, and control cables.  I plan to 
have the KAT500 & power supply in a weather-proof box at the base of the 
pole.

1.  Can I extend the AUX connections into the shack so the KAT500 will 
track the receiver?  If so, what kind of cable is required [I've heard 
CAT-5 will work?]

2.  Do I need to run any other circuits, other than coax and the AUX, 
from KAT500 into shack?

3.  Reno/Sparks is a high desert [4,500'] directly adjacent to the 
Carson Range and Sierra Nevada [really big mountains].  Winter temps go 
down into single digits, it does snow/rain.  Should I do anything to 
prevent condensation in the weatherproof box [light bulb, drain hole, ???].
