Topband: 75 ohm coax switch

[Herbert Schoenbohm]

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.
