Default If the ideal lenght of an antenna is 1/4 Wave lenght then wayare the Car Cellular antennas are longer then this ?

I always thought 1/4 length was easier because you can make one easily from 1/1 length
by breaking in half exactly two times.
And then you have 4, so more economic too.


A dipole is made from two quarterwaves. An odd quarterwave is
easy to match to. Any other length needs a matching network
of some kind. Gain comes about from directing the RF in
some directions. This can be one direction like a beam,
or omnidirectional with something more complicated then a
simple quarterwave antenna.

Tell your instructor he needs some more instruction.

Hey Jim, you ever do Echolink anymore?
Can I find you on an Echolink linked repeater?

Give me a time and place.

I'm about ready to take over *BALT* and kick those foreigners off
with a bunch of English in their ears. It seems they only do it
to link the two conferences together. I'll write the owner of that
conference. I've known him for years.

Email me at my callsign email addy.
This one is over 800 messages behind.


Hello, Scott
