A few years ago I thought this WWDX forum the best there was on the internet. I used to check in everyday to keep up with the 15-20 new and interesting posts per day, and 3-5 new threads per week. Now I find once or twice a month is sufficient to keep up with the next to nothing going on...

Yeah well maybe I'm just a little PO'd that you & your counterpart are out here misleading people, posting erroneous junk to sound like you're credible, and knowing that you know better or at least SHOULD know better disgusts me for the loss in station performance which following your advice...

I think the reason you need to keep returning to your near-field horse puckey is because the old Donald is still alive & well. You know we're actually discussing at or beyond the horizon as I've already previously mentioned and not on an antenna testing range. Keep it up, follow The DB and...

Hi Marconi, somehow I missed your post. I'm surprised you measured 13.75", my old CLR-2 was only an 11" bracket and the Penetrator a 12". I'm referring to the C-shaped piece which the rest of the base, including the coax connector, U-bolts and radial plates, attach to.

Nice try Donald but anyone can see it's the db following me around needing to be right about telling me I'm wrong, mistaken or "It doesn't work like that" and YOU backing him up. That you would post something so ridiculously wrong as "6dB per S unit" when it's been discussed on this forum for...

Wow, 274" for Ch.38? I wonder if someone replaced the hairpin with one custom made and was a bit off on the measurements? That might account for the extra radiator length. YMMV (Your Mileage May Vary) as they say, especially if any mods have been made.

Hey old goat 321, I received an email yesterday from a friend in SoCal who just set up his spt-500 at 272.5" total above the radial plate. I'm going to order up an spt-500 just to see how bad a copy of the original it is, and how it tunes. Just analyze it if you have an MFJ analyzer available...

Ok, see, you ARE smarter than that since you rewrote most of your previous post more correctly, or with excuses for the errors, except when you stated the fallacy, "Those are not near field differences but what you could expect in the distance" Because I would not expect something other than...

If only most of what you wrote wasn't false. When you shorten a 5/8 down to a 1/2 wave the impedance goes up not down because an end fed 1/2 wave is the highest impedance point an end fed antenna will be, that of around 2500 ohms +/- or the equivalent of about a 50:1 SWR - before the matching...

I'm sorry but you are mistaken about that.

If I'm reading your post correctly, quoting my post and using the word "You" as referring to me, well I apologize but you seem to have taken my previous post personally. I only quoted your post as an example of a forum user who tends to have looong long posts containing many paragraphs, and as...

Total length should be around 22' 6" to 22' 8" depending on what part of the band you're tuning for lowest SWR - PLUS the top hat. And make sure you bend the top hat rods down at 45 degrees. I'm curious, does the new SPT-500 use the old 12" base bracket or an 11"?

It's not that I can't post hundreds of paragraphs of technobabble, I choose not to. I just say it like it is and try to 'keep it simple stupid'. You see I'm not trying to deceive anyone into believing wrong is right so I don't need paragraph after paragraph after paragraph...

So to sum it up, buy either an Antron99 because so many A99 users are so happy with theirs, or follow the db down the garden path and buy a Maco. - but avoid the inferior performance of the full 22' long 5/8 such as the I-10K, Penetrator, Shockwave 5/8, Mr. Coily .64, Zero5 Colossal, etc. Ok...

No, I'm comparing the vertical polarization of my 5 element quad to the horizontal polarization of my 5 element quad. I disagree with your statement that a vertical will have a better DX distance when it might have a different angle than horizontal but when the horizontal angle is the correct...

Ok, enough circular reasoning What he asked was simultaneous vertical and horizontal. Circular polarization requires a 90 degree phase shift which technically isn't simultaneous. What I've found works best is vertical for local base to mobile and base to base comms, but horizontal for DX...

I've come to prefer a radiator length of 266.7" on all my 5/8 This provides a maximum of .64 at the ceiling frequency of 27.995 and an exact .625 at 27.400 I doubt there's much loss at all at the center of the band 27.185 even though it works out to a .6215 there, and .6165 at Ch.1...

I've owned several a99s, Imaxs, Sirio gainmasters and other fiberglass antennas and the one that most impressed me for big performance without radials is the Proton99. It beat the a99 and seemed to keep up with the Imax. It's only a foot or so taller than the a99 but 5 feet shorter than the...

The original hy-gain penetrator came with the top hat rods bent down at 45 degrees. If it doesn't tune when total length is about 22' 7" then try bending the horizontal top hat rods down at 45 degrees.

I believe it's basically a Vector 4K, a half wave very efficiently matched and elevated 1/4 wave by the 1/4 wave matching system at the base, consisting of a 1/4 wave down and a 1/4 wave up which, when added together, the 1/2 wave radiator and the two 1/4 waves comprising the base cone area, you...
