For years, I used Tyco DPDT relays. Open-wire feed, who knows what SWR, full 1.5 kW.
For example: http://www.mouser.com/ProductDetail/TE-Connectivity-PB/PRD-11DH0-110/?qs=sGAEpiMZZMtGt%252bn33CgIPz07uLBulijhRYGqdd4PmSw%3d Mine were 12 VDC units, and with a little research you can probably find them. 73, Hank, W6SX On Sun, Oct 20, 2013 at 9:04 AM, John Harper <j...@ae5x.com> wrote: > Morning all, > > > > I am planning to put in a DPDT switch (or relay) to allow me to easily > switch from using my 80m dipole as a vertical (T-top) antenna on 160m: > > http://www.ae5x.com/docs/antennas/160mT.jpg > > > > The dipole is fed with 450-ohm ladder line and used 10-80m in that > configuration so there is a high SWR on the line.
