Doesn't a MASTR II ps automatically compensate for low line voltage? Mine does. Sent from my Verizon Wireless BlackBerry

You might try building a 12 Volt DC supply, but, use a 120 to 24 or so volt transformer and regulate the output to the 13.6 VDC that you really want. Not ba real hard task. A box (optional), transformer, bridge rectifier, filter capacitor, regulator, some small parts. 73 Glenn WB4UIV At 01:22 PM 2/14/2010, you wrote: We've been given the opportunity to setup a remote receiver at the end of local local cable television provider's plant on the hill to help with coverage. Powering is the only issue we're running in to - currently the only power available within 6 pole spans is the 90 V AC plant power across the CATV coax. They've offered to cut in a power inserter at this location to feed up to 4 amps of 90 VAC to us (roughly 85 VAC at that point in the plant) - what is out there for a reasonable cost effective solution to convert this to 12 VDC? This stub of plant does not have RF across it, nor will it any time soon (RF removed when fiber backbone was overlashed on the same pole line). Our first concern was leakage but that shouldn't be an issue. 73, AJ, K6LOR
