I have an extra system so I am selling this one. I use basically the same
system myself

starts with the Grove TUN-4

the TUN-4 has:

two antenna inputs
switch to select either antenna A or B or ground
built in pre-amp
select the MHz band control
fine tune it control
you can bypass the pre-amp, choose unamplified preselection or amplified
preselection control
then feed TWO receivers from the back !

THEN I add two patch cables to go from the TUN-4 to your receivers
then I add 4 L adapters for the connectors if you need them

also included is a 12 V adapter

you can go to my web site and see two TUN-4's, I have replaced one with a 4
way splitter since two TUN-4's were too akward.
