Best shortest mobile CB antenna??

That's what I've been hammering away at DB over and over. A cap hat alone can't effectively tune an antenna without some inductance. The inductance could be in the form of a loading coil either base load or center load or a shunt coil at the feed point or both.This is what will match the antenna.

But the you say it is a contradiction though.


I think the problem here is symantics. An antenna can be tuned but not matched. Tuned means resonant. Matched means 50 ohms. Resonance does not mean 50 ohms.

This is whay I see here anyway.

If this is what you were trying to say, you were doing an awfully poor job because it is not what you typed at any point. Simply stating a device cannot in and of itself tune a shortened antenna is not the same as this description in any way. Why didn't you just say this before? It would have prevented many headaches for both of us.

That being said, your understanding of this matter is apparently not quite complete. You seem to think that all inductance is the same and all capacitance is the same, regardless of how it is added to the antenna. Unfortunately this is not the case.

How do I explain this... Let me think on this a bit, I know what is happening, but have never explained something like this before...

I been saying that over and over and over...now you finally get it!

What I saw you say was it won't work, not why it won't work. There is a big difference there.

That being said your explanation is not complete. Unfortunately this cannot be resolved with a simple explanation. What you are saying is true, assuming the load in question is in series with the antenna. The problem is a capacity hat is not in series with the antenna, it is in fact in parallel with the antenna. I mentioned this more than once, but you clearly either don't understand the significance of it, and/or have no idea that there can be a difference. Like I said, it is not the easiest thing in the world to explain, but I am willing to try, just give me some time to think over how.

Don't worry about it. What you are trying to think about is how you can explain it to look like you weren't wrong or better yet, mistaken with your previous posts.

Let it go already and let's move on.

Ahh asking me to back out? So do I comply and have you think you were right all along or not? Honestly, I don't care if you don't care, so I will take you up on the offer. I do suggest you do some more research, it is something I can explain given the time, and I don't need it to dig out of a hole, I was never in one.

I will inform you of this, your examples of what is happening with your antennas and what you say should happen are mutually exclusive. Your examples match not only what I say to a T, and match my model (and others as well) exactly, they also match the Generally Accepted Antenna Theory, where many people have run many tests over the years, and the word "theory" is really little more than a hold over. Hell, the first patent regarding a capacity hat was granted in 1898 so its not like they are anything new either. It is with your description on what should happen that you go wrong. Your description of what should happen and your own examples are contradictory, they cannot both be correct at the same time. I suggest you take the time to revisit your own point of view, at least to the point that these are more consistent with each other.

I wish you lived closer, I would say lets get together and do the cap hat with no loading coil experiment together. Oh well, opportunity lost... Who knows I may do the experiment myself one day soon just because... Its doing things like that that I enjoy about this hobby anyway... So what is the cheapest way I can confirm/deny what I, or you for that matter, are saying?

Anybody ever wonder what the best shortest mobile CB antenna is?
IMO - the Wilson 1000 or 5000. But they too have weaknesses, such as water intrusion into the base load coil. Wouldn't advise going any shorter that that except for the 5 ft FireStik - as previously mentioned. Anything shorter that these is where they get pretty weak . . .
