[Elecraft] Using XG-3 to Evaluate RX Antenna Switch

[Pete Smith N4ZR]

I recently built an 8-way hub for receiving antennas, using an 
inexpensive Chinese made remote control switch.

The switch works fine - at least the controller in the shack actuates 
the remote relays, but I'm quite suspicious of the actual RF performance.

Here's what I'm wondering - can I use the XG-3 as a signal source?  I 
was thinking I would connect its calibrated output to one of the antenna 
inputs on the hub, then go back in the house and assess the resulting 
levels on my receiver, both as a measure of throughput losses and of 
isolation from the other inputs.  The input impedance of the hub's 
antenna ports is somewhere in the 450-650 ohm range, because of a 9:1 
binocular transformer between the switch's output and the feedline, 
which is RG-6.

What do you guys think? Will I get any useful information from this?  
Will the transformer affect the RF voltage as seen on the other side of it.

Please be gentle - history major at work here.
