A three foot long base or center loaded A/S as probably as good as anybody's
3ft long 11m CB antenna. The K40's are a little longer whip but w/o
instrumentation I doubt you'd notice most of the time.

Bigger is better! [up to a limit of 102 inches for CB [27 MHz] use.]

A 62 inch antenna is about 54 degrees long. 90 degrees long is a full
size 102 inch whip. A 40 inch antenna is 35 degrees long.

Conclusion: a 90 inch whip is typically 'the best' for mobile, a 54 inch
antenna would be not as good as the 102 but better than the 40 inch
antenna. The 'short' antennas use a small coil to work properly. The
location of the coil contributes to how well the antenna works. But the
102 inch is still better than any shortened antenna.

I have a question about a CB antenna but I'd like an opinion from
someone
who knows more about antenna theory than the average CB'er. I have an
old
Antenna Specialists M-902 Black Stallion antenna that I am thinking
about
using. It looks like the one here
http://cgi.ebay.com/ws/eBayISAPI.dll...tem=3093592178 but I
don't
know how well you can see it. It's a shunt-fed, base loaded antenna that
is
about 3 ft. long and mounts on the trunk lip. My question is how does it
compare to some of the new antennas like Wilson or K40? Wilson claims to
be
the best http://www.wilsonantenna.com/w1000.htm but are they really that
much better? Thanks for the help.
