In several years of experience with Amateur (Ham) Radio, I have learned that there is significant attenuation of UHF and VHF signals when the transmit and receive antennas are at 90 degrees to each other.

Yet most Car Antennas are vertically polarized (some at 45 degrees) while most home based receive antennas (both cheap wire dipole and Yagi) that you can purchase are Horizontally polarized.

Why is this?


Do the broadcasters transmit with both horizontal and Vertical Antennas?

I ask this because I live 60+ miles from several FM stations that I like to listen too, and can receive them just fine with either my Car's Antenna or my Horizontally mounted attic based Yagi.

generater with the ability to rejuvinate its own magnetic charge and produce enough current to power a 60watt lightbulb for say, several years or longer? Imagine a group of these NPMD boxes hidden under your floor or in the ceiling powering all of your lights, possibly even 120volt outlets for standard appliances. The possibilities are endless.
