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. -- 73, Pete N4ZR Check out the Reverse Beacon Network at http://reversebeacon.net, blog at reversebeacon.blogspot.com.
