Has anyone tried the scantenna for transmitting 2-meter with no scanners hooked to it ? Or antenna switch. So not to overload the scanners. Just was wondering if it would work to keep from having to put up a second tower. Thanks, Jim
A good quality switch will have 50-60db between ports. Check MFJ, Comet, AlphaDelta. I used one for years with 50w on 2meters on one port and a scanner on the other, no problem.Al42 said:The standard coax switch has zilch isolation between radio ports, so I wouldn't use a switch.
Yeah, I tried it, and it still works well, no matter what people say. Of course, I don't live too far from repeaters, so that may be of good help. I get good reports, still on any of the three bands (vhf/uhf). I tx through a 75 ohm jumper to a 75 ohm splitter into another 75 ohm jumper to the Scantenna with no problem at all. SWR is less than 1.5/1 on the bands.TeRayCodA said:Ummm...Are we talking about using a scantenna,with 75ohm coax,and a 300-75ohm balun transformer?
Sounds like a bad idea,be careful....
I went back and checked switch specs in the catalogs and most say 60db 1-30 Mhz and 50db at VHF/UHF. I've never actually measured one, it might be fun on a rainy day. Like you said, I think they must be made in the same factory because thay all look alike.kb2vxa said:Hi Dent and readers,

Thanks Grotz, I use an MFJ-1704 four position switch to use the Uniden scanner, IC-706Mk2G, Alinco 222MHz rig and an Azden 2M rig dedicated to packet radio on a 2M/1.25M/70cM vertical and all is well. MFJ is the cheapest and is electrically the same as the Comet, AD and the others, the best buy out of the lot.
Al, considering how many times we've told them, do you think they'd get the message there is a difference between a coax switch and a coaxial switch? (;->) Oh, does the name Dow Key come to mind? They're baaaaack.
