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 closer to the power
lines. I would like to hear from anyone who can say they are not a good
and affordable means on switching Beverage feed lines. I also have
several MFJ remote switches using the RCS-12 that I do not trust as the
relays are sometimes giving false reply due to the design of the pass
transistors in the Ameritron. For the amount of money in that a Dynair
costs it can't be beaten, if fact I would have purchased this one but
the vendor will not sell nor ship to the Virgin Islands

So here's the deal. Buy this one and try it and if you don't like it's
performance I will pay you double for it. They are getting very rare as
most TV stations are going to digital and these passive switches one
can't even find in the security company catalogs anymore.

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??

Subject: Topband: 75 ohm coax switch
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?
