Re: Looking for power injector for amplified antenna...

Well, whatever used to be a standard, now his booster uses 6VDC. Ask the chinese, I did not do it... :???: Seems the USB jack current is capable to please the antenna booster. I will not complain. Specs here show 6V/100mA ----> https://www.ebay.com/itm/192285092531?chn=ps&norover=1&mkevt=1&mkrid=711...

Worked too on 5V. :eek: If can work better, I do not know, but will live with it. The second schematic here ----> https...

Looking for power injector for amplified antenna...

Hi all. A TV antenna on the roof has a built-in preamplifier. Am looking for a power injector that will send 12V to the antenna and will separate the RF signal to feed the TV RF input. Do you have one behind the spider webs for sale ? Should have three ports; - Power in - connects to 12V supply - Po...

Those places harbored some (or now very...

Hi. Cheap and not multimeters have the Hertz reading setting. Would like to implement a simple optical reader aiming a turning shaft with a black/white marking. Perhaps severing the optosensor half of an optocoupler, or a phototransistor, or even a tiny magnet glued to shaft, and a coil to the meter...

Hi John.
Seen a TV remote control emitting commands by itself caused by a nearby idle cell phone.
