Antenna Diode
radio antenna power? ?
If I were to take 20 feet of copper wire and attach both ends to a 10-volt voltmeter with one end to a diode, will the voltmeter get a reading? I know that power can be generated from radio frequencies created by power lines and radio stations and I live close to both.
Yes, you should be able to pick up a reading.

Winegard AP-8780 Preamp for TV Antenna $49.99 Improve your reception of both VHF and UHF signals with the ANWI8780 from Winegard. This inline preamp mounts to you antenna mast for convenient placement. The 17dB average gain for VHF and 28dB for UHF easily overcome any signal losses due to the length of your coax cable. A fast recovery diode and advanced circuitry virtually eliminates transistor burn-out. The high impact ABS housing protects the preamp from the elements. Specifications: 75 Ohm High Gain, Low Noise Avg. VHF gain 17db, UHF 28db Selectable FM Trap Features: Universal housing can be used with any off-air TV antenna. Made of high impact ABS material, mast mounted for easy installation. Flexible polyethylene boot covers on 75 ohm;. Zinc-plated steel hardware; all mounting hardware Selectable FM trap reduces FM signals (88-108 MHz) -15 dB to prevent overload, tunable FM trap reduces a 3 MHz band width by -12 dB. Both adjustable — switchable without opening the housing. Transistor burn-out virtually eliminated with specialized circuitry featuring fast recovery diode that protects against lightning-caused pulses. Operating temperatures -40° to +140° F. 117 VAC UL and CSA approved power supply is included. (Does not include F-connectors.) |
