[Elecraft] New KAT500 pics from the Visalia DX convention

I believe that the accepted figure for the loss of one PL-259 connector is about 
0.01 dB at 50 MHz, and this is a very conservative (pessimistic) estimate. You 
will find measurements on the web that vary from 0 dB to 1 dB for a single 
PL-259. The (female) SO-239 is a bit worse, but if you use 0.01 dB for each 
connector regardless of type, you will have a pretty good, conservative estimate 
of the connector loss in your system at HF.

The typical ham has about 20 coaxial connectors in the path between transmitter 
and antenna, representing a total loss of about 0.2 dB (conservative) 
representing about 4.5 W loss for every 100 W of transmitter power. To me this 
seems like it's in the (very conservative) ballpark.

The loss increases at higher frequencies, as you can imagine, but it's also even 
lower at lower frequencies.
