I'm sure that's high performance microwave certified hot glue (from Lowes) and
not the common garden variety kind (from Home Depot).

The feed for 13v to the antenna was a ferite bead with 3 turns, it was attached
to the board with orange hot glue. It connected to the 13v input to the
ua78m06, for the mod I added a 7805 from the 18v lm317 to the bead rf choke.

Have been using a sat passive splitter and most of my cables are using F
connectors so I'm thinking of modifying a DTV multi switch to provide 5 volts
instead of 13 volts on the LNB/antenna port. Antenna is a Trimble bullet II 5
volt antenna. The switch is active and I would ignore the 22Khz
I've opened it up and it ( a eagle aspen DTV4X8 ) has two lm317's maybe for
18 and 13 volts as well as a ua78m06 for the amps and volt/22Khz switches.

Hi
There's a *lot* ore in there than in a normal GPS splitter.
