Can I use PI 21 to power Terk ota (clip on dish ) if I run seperate cable to Terk from PI and then connect other end from PI to tv/ant input on HD TV. The Terk was using power from receiver (18V ?) and PI output is 21 V.

I got the Terk for free, but since I'm HD , I can't diplex it so I'm thinking this would work. Local channels go down here occasionally, plus there are extra locals not on Directv

I don't think the Power Inserter is compatible with your Terk antenna.

The pi itself would probably work but you can't power both the dish and the antenna with it.

Your right, I'm only looking to power the Terk by itself with seperate RG6 cable, that would connect at the Terk ,then come into the house to PI , then from PI to ant/ input at TV , plugging the PI in only as needed for backup to locals.

21v power supply feeding a 18v device generally should not be a problem. Most electronics have regulators at their input that would easily discard the extra 3volts. In some devices you could probably get away with the 29v power inserter too, it just depends on the range of the regulator in the device's power supply.

The more important factor would be current consumption but since the LNB power inserter has a higher capacity than the antenna would ever pull you should be ok there.

Most of the clipon type Terk antennas are not amplifyed and no power is needed for them. if you have the older type and plug a power inserter to it, you will have short and blow up the power supply.

If you have a amplifyed type clipon, it should have come with a power source.

Never mix devices with unknow power supplies unless you really know what there specs are and what you are doing.

Cable t, the model Tv44 Terk ( which I have) is powered by the receiver according to the instructions , I'm thinking is 13V to 18V, so it requires external power.

Big, I thought about the power draw also, I think the PI max amps is 1.5, I can't see the Terk pulling more than milliamps, but it would be something I would watch

Exactly, it seems you got what I meant regarding current. I think I read something earlier that when using that Terk antenna connect it to the 18v side of a legacy switch. So 21v supply should workout just fine for you.
