What do you use for switching your receive antennas? I have been adapting the RG-6's F connectors, to PL-259s to use a regular ham coax switch. The 75 ohm (TV) type switches show a minimum frequency

It's easy to homebrew something using small-signal relays. This has all sorts of added benefits (remote control, automatic switching, etc.). There have been lots of discussions on here about the corr

Yes....Find on eBay an old passive video switch like the ones made by Dynair. (1x6 or 1x12) Not only are they designed for 75 Ohms they terminate all unused feedlines (RG6) with a 75 ohm resistor. Th

Most TV switches work to DC, even if they say 5 MHz. There are many switches around. How many positions, and is this indoors or outdoors?? What do you use for switching your receive antennas? I have

I have used Dynair switches for years and rout all my Beverages through this switch with excellent performance on 18 Mhz will chasing some rare DX I could not hear on my 3 element WARC beam being clo

Thanks everone for the ideas. I hadn't thought of the Dynair video switch. Access to useful information is why I joined this group - and haven't been disappointed. Tom, receive switching will be in t

In the shack, some video switches are OK. Be careful. Many switches have active components and/or are pretty poor up high in frequency. I'm not sure about modern manual CATV or MATV antenna switches,
