[QUOTE="jeallen01, post: 998398, member: 176704"] A combo of the following: - a bog standard 230Vac/15V dc wallwart that I had lying around - a home-brewed filter with heavy capacitive/inductive filtering to try to take out any EM crap from the PSU, and a 15V zener to make sure the o/p did not go above that - am actually getting about 13Vdc out of that & could probably have used a higher voltage PSU and an 18V zener to safely get more like 16-17Vdc o/p to the amp itself, which is a standard dc pass satellite unit for 47-2150MHz IIRC. - an inline DC inserter module intended mainly for supplying head-amps for TV reception Will provide more details of the filter and dc inserter module tomorrow if you want (just going to bed now). Also, I aimed to be able to inject about 40mA into the inserter module in case I wanted to add a 2nd amp about 1/2 way along the cable as each amp consumes about 20mA. However, I've since come across [URL='https://www.cosycave.co.uk/product.php?id_product=241']this unit [/URL]which effectively combines all those with an inline amp to be used near the receiver - that's a lot cheaper and quicker, but would not work for me as my antennas are some way from the house, and I aimed to have the amp as close to them as possible.
