Coax Switching Boxes (receive only)
 

Hello,

I would like to purchase an "inexpensive" simple, coax antenna switch for
occasionally switching two antennas into my scanner.

Freq. range up to about the scanners limit of 1.3 GHz

Receive only.

Looked at the Daiwa, and for the $ seems like the way to go, but I thought
I'd ask first.
Any opinions on the Daiwa ?

Any others to consider also that aren't too expensive ?

Ace hardware has a coax switching box, I guess for TV's mainly, with
pushbuttons.
Think this would do the job for my scanner stuff, or probably just junk ?
It's really cheap at about $8

Thanks,
Bob

A CATV A-B switch? It should only be a few dollars. Although the spec
may only be up to (say) 870Mhz, they are probably OK (for your purpose)
to 1.3GHz +.

Bob,
Receivers just aren't as 'picky' about switches as transmitters are,
so almost anything would probably work just fine. If you're into
making things instead of buying them, a look in the junk box would
probably be profitable. If not, then ... whatever grabs you.

The one parameter receivers are "picky" about is port-port isolation.
Switches made for HF switching will likely have very poor port-port
isolation at VHF and above. The result is the receiver hears the selected
antenna and some of the unselected antenna. This may or may not be a
problem.

A decent cable TV A-B switch should have an isolation of at least
something like 40dB at 870MHz. [I think I measured an old Jerrold switch
as being around 70dB.] While probably less at 1.3GHz, it's probably
still sufficient.
