I suggest that you go to a library or obtain a copy of the Amateur
Radio Antenna Handbook. A good starting point.

I tried to build a few antennas for CB. Too big to deal with.

2 meters antennas are small, portable and get good gain.
Plus, the range on VHF-FM is incredible. 50 watts will
talk farther then 120 watts of sideband on CB.
(not including skip, tropo or other enhancements)

Look in your library in 621.384 A.

Inverted V antennae are not so bad. I tend to agree that a full wave
loop is a bit large at CB frequencies to manage, doable if you have
patience.

Quite true.

First impression on this statement makes me a bit weary as to its
validity as a general statement. Especially if you are considering
line of sight communications.

In a more specific case it may very well be so. Trying to make a
general statement that "x" power output at "y" frequency yields better
distance than "w" power at "z" frequency may not always be true. The
major effects on communication distance is determined primarily by
transmitter and reciever antenna hieghts. Given equal antennae hieght
for both bands, and equal gain, then one can better compare distance
versus power.

It maybe true in your case. It may not be true in all cases.

Thats right, very good audio quality, much lower noise, 2 meters is the
best, CB sucks.

I was on my CB last night. I used sideband and some AM. I also
made a quick 2 meter contact. The noise level on 11 meters
started out quiet, got up to about 3db, then dropped back
down an hour later. About the time the static went up, there
was a bit of DX. Not-so-local signals were wavering a bit.

My 2 meter contact was only a few miles. It was the last
radio I used. Tuesday nights are 11 meter SSB net nights.

If you're in the mid-atlantic area, try 36LSB at 1930EST.
There are check-ins from MD, PA, DC, VA and DE. We don't
get west because there are mountains in the way.

Make that 36 USB.

Well at 27 MHz one is still plagued with atmospheric noise such as
lightning and manmade noise. In most instances it will overcome teh
galactic noise from beyond the atmosphere. At 2 M and above galactic
noise is more prominent but at considerable lower levels than the sky
noise at 11M. Around 20G or so comics rays become a noise source.

Also FM has advnatages in reception in that most noies has amplitude
components that are averaged out in FM detection. The major noise that
FM has to overcome is the thermal noise generated within the receiver.
