2. All used at 1.5 : 1 match or better

The match for each antenna was not listed, and I can only assume
that they were different. Regardless, what was the forward power
with each antenna, and why was that not listed?

No need



Sure there is a need was the antenna tuned for max field strength or
lowest SWR. There is a difference you know even though Lancer doesn't
know it.


Why don't you explain why max field strength and lowest SWR don't
occur at the same time? As you have stated that you know.


Better yet why don't you tell me why they do occur then, prove how smart
you think you are. LOL Go wash off assclown

No, your the one that pointed it out.....

No, I'm the one that pointed it out a long time ago. And there are several
reasons why it happens, but the most significant is because nothing in a mobile
installation is perfectly grounded. The RF ground in a vehicle is the vehicle
itself, and at the frequency of interest (27 MHz), it rarely shows the nice low
impedance needed for a good ground plane, or 1/4 wave resonance to work as a
counterpoise. So your meter might show a perfect 1:1 match, but the meter will
be wrong because it, too, is referenced to the same imperfect ground. The -only-
way to be sure you are getting the most signal from your antenna is to actually
measure the signal, and you do that with a field strength meter. You can see the
difference for yourself by doing your own test. Assuming you don't have a dummy
load for an antenna, you will see that the best match does not necessarily mean
the best field strength.

I thought this topic was already hashed out a long time ago.....
