A pole? Why would you need a pole on a mobile? To get it above the roof line? I guess that wouldn't hurt things, just extend the feed line another 18 feet or so, right? Or if it's a really long pole, maybe 18 feet on both sides of that duali antenna set up, that ought'a work, hadn't it? Marconi, sometimes you just ain't 'right', right?

Yea, it depends a lot on what you have been drinking and how much---while sitting in your easy chair 'Doc.
If this is not your excuse for misunderstanding my words, then maybe a visit to the local Optician. Then again, it could be a whole host of other problems developed during your childhood.
Do a google on: (What does the word "poll" mean?) and get someone to help you figure it out.
So a fatter antenna means louder modulation hey? I guess I'll just forget about the speech processor and save my tube finals a bit and run a dipole antenna made out out of 3 inch wide copper strap instead of 14 gauge wire. 
You know, this is TWICE that i've seen statements this week on CB forums that state that an increased surface area of the antenna (or coil) causes gain or "increased modulation". It's been fairly well tested and documented that the coil wire diameter can affect the number of turns needed to a point. And the few number of turns, the better when it comes to efficient antenna design. The design of the coil directly affects the amount of loss (power dissipated as heat) from the coil. However the statements (like above) being thrown out by people about these CB antennas are just ridiculous. Are people making this shit up, or are they really trying to understand how antennas work and just misinterpreting what they read? I actually mean that as an honest question...it seems that too many are just parroting something they heard from someone else that was misinformed. When will it stop?
You know, I'm trying my best to learn and understand everything I can about antennas and what makes them work. It's been educational and more importantly to me, fun.
I have noticed the parroting cheerleaders growing in number recently. It's another generation of the 'Piss and Vinegar Pep Squad' spouting ridiculous claims with no merit. For some reason people think that theory means nothing and that there is actually some secret magical potion being brewed in the garage of a mullet sporting ex-car stero salesman in Hicksville, USA. Too bad that smell is actually BS and snake oil.
'Billy Bob keyed on Pork Rind and he was running a new Triplex Doppler 9200 made from super secret technology found when they moved the Colonels 11 herbs and spices.'
I sometimes hope and wish for that magical potion myself. Maybe we all hope that maybe the next gimmick is for real. Sometimes you gamble and lose. Instead of listening to reason and proven technology we just go out and buy a Merlin.:headbang
What it amounts to is working to learn something. Not many people enjoy that 'work' part of it (four letter word, right?). It's always easier to take someone's word for something than to find out for your self. Guess that depends on how knowledgeable that 'someone' is, and that's a good question all by it's self. If something has been around for a while, then you can be fairly certain that almost anything you can think of has already been tried with it by someone. Finding that 'try' isn't easy, and finding out why it didn't work is even not easier. So, it's a fairly safe idea to go by what is sort of 'common' knowledge in the appropriate place/science. The 'trick' there, is determining the appropriate 'place'. That's the only 'secret' in doing dang near anything. And that's soooo easy, isn't it?? The alternative is making all those mistakes by your self! If you should live so long, good luck!
There's a bunch of stuff that goes over my head. Mainly cuz I'm too lazy to do the learning to reach up there and grab it. And since I don't do the 'reaching', I ain't gonna do the 'teaching'!

the low-down on antenna coils is here:
Mobile antennas, short verticals, loading coil loss,and loading coil current
The big picture of antenna coils is the diameter to length ratio of the coil, not just the wire diameter. I would say due to skin effect, the plating material (low resistance) on the coil wire is more important than the wire diameter.
As far as the diameter of the rest of the antenna: A thicker antenna should have less Q, meaning wider bandwidth. Google for cage dipole or folded dipole.
This claim of louder audio is CB salesmanship. If you want to sell something, you must tell the customer what he wants to hear. And CBers want louder audio. sold!

Or you could just buy a JoGunn with "audio gain."
EXACTLY! Another case of bullshit sells. WTF is "audio gain" when talking antennas anyway?
Reminds me of all the "colour" TV antennas we used to see advertised. My old B&W antenna worked just as well. Somewhere sometime someone talked all over someone else and that made him a God in CB land. From then on anything he said or did became the gospel and the truth be damned.
Mole...I think you call it "Uneducated people trying to sound intelligent". I'm not educated enough on the subject (antenna) to comment.
