[QUOTE="Llew, post: 975185, member: 175007"] Very neat VS, bombproof. +1 for the name ;) My LNA4ALL is now at the antenna head, getting >100 flying machines now. Had some hiccups providing phantom DC at the correct current level to the device. I needed to lower the current limiting resistor to 47R from 100R in my Bias-T design, as it was only providing 40mA at 4.5v to the LNA4ALL over the extended coax. It's now 6V at 60mA. I really need a decent power adapter for the Bias-T, instead of the usual rubbishy unregulated ones I seem to have dozens of. [ATTACH=full]94267[/ATTACH] [/QUOTE]
