Dual Feedline Option

This option is very useful for allowing a single beam in a stack of phased beams to be switched to a second radio's feedline.  Paired  with the StackMatch or StackMaster control's "auxiliary" position it gives the contest operator that fast hit and run weapon to break that pileup on a multiplier with a bigger antenna, while running your own pileup.

A special modification of it makes it a TwoPak which is a HF-VHF (150MHz) Antenna DPST 10 KW Relay.  It is capable of 10 KW Power handling to 30MHz, 5 KW at 6 meters, 3 KW at 2 meters.

It also can be used as a stand alone high power high isolation R.F. relay to select between two antennas.  Think of it as a SPDT RF relay  that can also be used to select one of two antennas and feed them to the StackMatch or StackMaster.

It comes enclosed in a heavy duty die-cast Aluminum box  approximately 4x3x2 inches in dimension.  It has a three SO-239 connectors (N-type optional), Galvanized U-Bolt,and a two conductor un-terminated wire for attaching to the 12vDC control line.  

The dual feedline switch has >80 dB of isolation between ports, and will handle 5KW CW, and RTTY.     It will operate from DC to 55 Mhz.
