Not up to date....

[FLHT Ron]

Okay so I was listening to music today until my 8-track tape got eaten!! So I slapped a beta into my machine and turned on the black and white tv I have! Then it dawned on me! I might not be up to date electronically!

Could someone explain VHF radios to me as opposed to CB's! I've looked them up but can only find marine units! Do you need a special license? Does it take a different antenna than CB's!

I know! I'm electronically challenged!!!

Thanks Pipeman! The only time I've ever heard of these things being used was on boats! Great idea for trucks though!

RonRecption is good at time up to 50 miles.

Very clear signals.

thats ok, if lawmakers get their way, pretty soon the old adage of "your just a steering wheel holder" is gonna be more true than people think

Here's the technical difference - VHF means 'very high frequency', a range of frequencies between 30mhz to 300mhz.
CB is short for 'citizens band', a narrow slice of frequencies around 27mhz.
The earth is surrounded by ionized particles that always refracts a range of radio signals back to earth, far over the horizon.
As it's strength varies, the frequencies it refracts varies.
The stronger the ionization, the higher the frequency it bounces back to earth (or "skips").
In daytime it increases and at the peak of the eleven year solar cycle it intensifies even more.
At the bottom of the solar cycle, in daytime, usually signals up to 25mhz can 'skip'.
At the peak of the cycle, sometimes frequencies as high as 50mhz (rarely) can skip.
Because VHF signals are higher frequency than CB signals, they punch straight through the ionosphere, hence VHF is almost always line-of-sight only.
CB signals, at 27mhz sometimes skip.

And antenna size is related to the frequency. Think of it like a whistle or flute - the shorter the flute the higher the pitch, this why VHF antennas are smaller than CB antennas.

And the Billy Big Riggers that slant their CB aerials forward at a 45% angle lose signal as the Band wave is horizontal. Hence, by slanting the aerial, the parallel distance from top to bottom os less than if the antennae was straight up and down.

But Billy Big Rigger doesn't care as long as he looks cool.
