If you have the most common version that requires an SO-239 mount... https://www.sirio.store/index.php?main_page=product_info&cPath=2_88&products_id=397 Here is an Amazon link to the mount by it self. ... or not, the forum is trying to insert an amazon link as a media file??? Odd. Anyway...

A few things. I wouldn't call it a "bazooka" antenna, although I can see some physical similarities in said design, electrically it is not the same. It looks more like a sleeve dipole to me. I don't know why they are using the antenna's velocity factor for an external dimension. The coax's...

Its best to use a balun, but you can go straight from one to the other like AudioShockwav shows. You can also get antenna tuners that have said balun and parallel feedlline outputs built in, and their are also link-coupled antenna tuners as well. Its actually primarily the domain of hobbyists...

Twinlead, which has two wires held apart by a solid piece of material, no openings. Window Line, which is basically Twinlead with openings in said material. And Ladder Line, which as stated above looks like a ladder. In the past, these were seen as three very different things, but today...

So your Procom antenna mounted at 30 feet will outperform the ground mounted 102" whip that started this thread, or the one mounted to the gutter of a mobile trailer mention above... So, which one would be better if you mounted said proton on the ground or at the level of the gutter of a mobile...

This is absolutely true. When someone gives numbers of one vertical antenna over another, it is almost always with both of them over a flat, perfectly conducting, infinite plane, which doesn't actually exist in this world... In the real world, you see far less of a difference than even this...

I'm actually aware of this, heard it was coming late last year, and saw it live a few days ago. I will have to see if I can get it running on wine in linux as I don't run windows on my main computer. I have run tests between 4nec2 and eznec in the past, they produce very close results. The...

Comparison of Imax models with and without capacitor at 20 feet above the earth. No mast or radials were included in these models.

Comparison of Imax models with and without capacitor at 30 feet above the earth. No mast or radials were included in these models.

Comparison of Imax models with and without capacitor in free-space.

I got some of the modeling I want to do done, here is what I have so far. All of these are models of just the antenna, one in free-space, one at 20 feet above earth, and the last one at 30 feet above earth. None of these have mast or feed line, or any form of ground plane attached, that is...

I don't recall what specifically I used for the overall length, and I don't recall where I got it from, I want to say the imax exposed article that has been floating around the web since long before that, but am not sure. I think I would disagree with this, as its not the % of overall length...

If you look in the imax thread I created not long ago (here is a link), the quotes contain a link to the direct messages I found said data in. Unfortunately I haven't been able to add to that thread lately as I have been working long hours, but I want to model the antenna with and without a...

Balanced antenna? That would imply being center fed, unless there is another way to try and balance a vertical antenna? So its a T2LT or perhaps a Gainmaster style of matching? I would lean towards the T2LT type as that can handle quite a bit of power on its own without a matching circuit...

The old way of using pics from albums appears to not work with the forum update, so here are the images above, this time uploaded straight to this message, I think... The first one is the imax without the capacitor, the second one is with said cap. The DB

I would also like to know this. The DB

There are ham radio contesting stations that have massive towers with the several of the same antenna at multiple places on said towers. They not only switch between antennas, but also run some or all of the antennas in phase, which all affects the angles that said antennas are sensitive to...

For those interested I have found some of my models on this concept, they are posted on the forum in this thread. I didn't put them here because, even though it took up over a page of posts, it really is off-topic to the thread as a whole. The DB

I thought I lost all of these models, but apparently I haven't. I'm not sure when I made them, but it is in a folder listed as before 2020 models. One thing I am certain of is it isn't my original imax models meant to test weather a capacitor was present or not, the techniques I used are more...

@Chris120 now your just making things up. I would personally say that you are projecting your problems onto me, just because I had the gall to call you out on your trollish behavior that apparently you think is acceptable because 'this is a forum'. Anyway, I'm done with this. I will let the...
