I recently acquired one of these 3PDT relays: http://www.ebay.com/itm/Leach-Relay-Model-1177-CBF-115-Volt-50-60-Cycles-Coil-374-New-Old-Stock-/121209541061 I have an application to cold-switch sectio

That relay is fine for switching coil taps but doesnt appear to be what you need unless you wire sections in parallel and use a relay for each band. Since youre switching at a low RF voltage point th
The open frame relays are suitable for that purpose, there no need at all for coaxial relays 73 Peter Nope. You need something like this: http://www.rfparts.com/relays/relays-coaxrelays/6350-6.html _
I should clarify ... this is for a wired connection ... to bring the 160/80m coils in and out of the circuit: http://www.ad5x.com/images/Articles/Match43footerRevA.pdf I think that his original desig
Carl, I know that you won't be surprised that I missed the need for two rather than one relays ... sigh. I'll either have to get two of the ones he recommends: http://www.galco.com/buy/Deltrol-Contro
Dunno but before you buy anything, look at http://www.ur4ll.net/#relays You might find something eminently more suitable and at the best possible price and service second to none. If you have Skype,
Wow, that's an interesting collection of stuff! Thanks for the link, David KD4E Dunno but before you buy anything, look at http://www.ur4ll.net/#relays You might find something eminently more suitabl
I also missed the antenna impedance which will create some high RF voltage on 160 in particular. That is a latching relay and not suitable for what you want to do if Im understanding that matching ne
Those Leach relays were designed for switching RF. Depending on the impedance and thus the voltage, they're OK for over 1kW. I have picked up 24 volt DC ones for $2 a time in the Dayton flea market..
