Have a customer with a Dish 722, and the TV2 is wired up via the old line that ran from the 722 location to the old 500 dish and then back down the other lead to the TV2 location.
The 500 dish was removed (left mounting foot on roof) and the 2 leads were barreled together.
The 722 couldn't use the 500 dish location as 129 was obstructed by a tree, so the HD dish was installed fairly close to the location of the 722 on the roof and the coax ran behind a strategically placed downspout.
(customer has brick home and is not eager to have coax on the brick)
Roofing crew replaced shingles, and did not realize the loop of cable on the old mounting foot was in use, and they snipped the wires at the soffit. New flashing went over the soffit, so those wires are gone for good.
I can run coax around the back of the house and get kinda close (12 feet or so) to TV2 except that the ceiling is drywalled, no possibility of a wall fish, and customer not thrilled with any wireless options.
I was considering taking the A/V output from TV2 and running it into a channel 3/4 modulator and going in RG6 as far as possible, then using baluns and poking 300 ohm flat lead under the carpet.
I'm thinking I have a better shot with VHF-lo channels than using the onboard cable/UHF modulator on the twin lead due to it's lack of shielding and generally being obsolete.
Has anybody tried this ?
I have a roll of 300 ohm flat (don't laugh, figured it might be useful someday for something) and can dig up a pair of baluns. Just not eager to try it in front of the customer (lay it out first and see if it works before poking under rug) and have it not work.
Plan B is wait for frost to go out of ground in the spring and trench in cable. Not eager to do that either for obvious reasons (I'm old and tired).
