[IRCA] Cable connectors



Recently I bought some items that may be useful for antennas. The first is an adapter that combines four BNC cables to a single CAT5 type cable. It's meant for video use which runs from essentially DC to 4MHz. To test it I checked the S-Meter for both 550 and 1480. Then I removed the RG-58 cable and swapped in the CAT5 with one of the adapters on each end. Both S-Meter readings were the same.

They also sell video ground loop isolators. That puts a transformer on the end of the RG-58 BNC connector. I did the same test as above and got the same results. No drop is signal strength.

I do like the ability to run four separate signals down one cable. Especially since CAT5 cable is cheap and easy to make the RJ45 end connections.

FWIW...
