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, I've seen them up to 4 way years ago, and they are usually much better.

Personally, I use relays with a desk mounted control. Saves having multiple heavy wires on the desk.

160 is pretty forgiving for switch construction, provided the shields are all well grounded to a common shield plate. Do NOT switch the shields!! Just switch the centers.

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 the shack. I have 4 antennas on the
mechanical switch now, but anticipate 6 before winter or divorce. :)

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 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 of 5MHz.

Is there a better solution?
