[Elecraft] KATxxx Remote Tuner

While I prefer unmatched antennas fed with very low loss ladder line, I have always felt the tuner should be at the feedpoint of that line.  When I added the KPA500, I switched to the KAT500, and it’s not really practical to locate that remotely.  As a compromise, I am using a short (maybe 15 feet) length of coax from the KAT to a hybrid balun (1:1 / 4:1) in the attic which connects to the ladder line.  I actually notice no difference in performance (everything else remains unchanged).

 

That being said, a “remote” version of the KAT500 (or a KAT1500) would be of immense interest to me – so I will follow this thread closely.

Eric/Wayne,

 

Has there been any work done for a potential dedicated remote antenna tuner?

 

A remote tuner that could handle 500 or 1500 watts to match up with amps power wise (Or just a barefoot K3/K4). Maybe a black box between the LAN on the K4 or ACC on the K3 so control signals could be sent to the tuner via the coax.

 

I’m a firm believer in 50 ohm matched antennas, but if a tuner is required it needs to be at the feed point.
