Thanks
personally I prefer the Solarcon version, but everyone has their own
favorite, If you really want a decent vertical, pick up a good 5/8
wave ground plane Maco makes a decent one.

Agreed, Keith. If you have deep pockets, the Mosley 5/8-wave ground planes are
hard to beat. Not in performance, but in construction. A well designed 5/8-wave
is a 5/8-wave is a 5/8-wave, in terms of performance. Their Devant series cost
over $300 though. I'd say try the Solarcon IMAX-2000. I'll provide the link for
you "high-rollers" anyway.

Solarcon has a plant not too far from where I live, in fact I have a
friend who works there.
I have never seen any of the Devant Special, or Devant 1, 5/8 antennas.
The Devant Special has a Top-Hat, that slightly loads the antenna
capactivly, allowing for less Impedance Matching circuitry, allowing for
less loss in the matching circuit. And is advertised a having 3.4 dB
gain as compared to the Devant 1, at 3.0 dB, that does not have a
Top-Hat assembly. No dB gain references are given, but are probably dBi
figures.
These antennas use only 3 ground plane radials, and I have measured the
difference between 3 and 4 ground plane radials, as the 4 ground plane
radials, give the antenna a wider bandwidth.
They use what they call a "Induct-O-Match" Impedance Matching, parallel
then series inductor matching system, same as seen on the MaCo V5/8, the
Penetrator 500, and a few other antennas.
The antenna is 19 feet tall, 228 inches tall. The Penetrator 500 is 257
3/8 inches tall. The performance is probably still very close, even
being shorter.
But its a light weight, none reinforced, tubing fitting into smaller
tubing type construction. I am sure it can be easily reinforced, not
like the foreign
type antennas, with there cheap vertical ribbed tubing, and odd ball
sizes.
Its probably a good antenna.
I have a I Max-2000 that a guy wants Ground Plane Radials installed onto
it.
We will see.

RatCrap used to sell a version of the Shakespear "Big Stick", colored
a lilght blue.
Way to tell what it is:
If it's in two pieces, it's a Big Stick copy.
If it's three pieces, it's an Antron 99 copy.
Performance-wise there's not much difference, although IMHO the Big
Stick seems to be better made (stronger). Either way, for only $25
it's probably not a bad deal.

Ten bucks!!! At least Maco lets you download theirs off their site.

Yeah, I have a bunck of old CB magazines fron the 70's. I realized that my very
first base antenna was a Cushcraft CX-1000. It looks like a Maco V58 without
the radials. It was advertised as having 3.75dB(?) gain. Probably a 1/2-wave.
Worked well though.
>I have never seen any of the Devant Special, or Devant 1, 5/8 antennas.
I have, on a former neighbor's house. Gotta say...it did look good. I'll likely
never own one at that price though. Here's my 11-meter summer project.

Sounds good. :-)

I'm only on chs. 36 through 40 now. I remember an old Archer (Radio Shack) CB
base antenna that used a similar configuration.

Just a different shape, eh?

I'd love to find an old AS M-800 Super Penetrator. That was a 5/8-wave. See, I
do my homework...sometimes. I still have that M-400 NIB. :-)

For $300, it shouldn't need to be reinforced.

For $300... (You get the idea.)

Can you do this? I don't think the matching system employed was meant to be
used with radials. Copper just sent me an advertisement about their new ground
plane attachment bracket for the IMAX-2000. Dunno, you tell me?

Lemme know.

Yes the MaCo Antenna wed site is truly a treasure for CB Antennas.

Yes Radio Shack sold a Hy-Gain CLR-II, a almost 5/8 wavelength long
vertical, with 3 ground plane radials. This was the second attempt by
Hy-Gain to have a 5/8 antenna. The first 5/8 vertical from Hy-Gain was
called the "Golden Colinear" it had a single point mount that held the
vertical element, that broke, after a short period of time, I have never
seen one of these antennas, just the advertisments.
Of course next came the Penetrator 500, that was advertised from Hy-Gain
to take 1500 watts, since the CLR-II had a small impedance matching coil
on a small round circuit board, mounted in the base of the antenas lower
insulator, that would easly burn up with to much power.

Yeah ah lot guys would love to find a new Penetrator 500 new in the box.
I have a few of them. I have bought them off the internet and such. Some
where in great shape, and some didn't have one straight piece of tubing.

For a vertical element that long, I think a few extra pieces of tubing
is not out of line.

Its a possibility that the impedance matching rings may only need a
slight tweak for the SWR adjust-O, don't know till I modify it and test
it.

Oops, my bad. That's AS M-800 "Starduster II," not Super Penetrator. The AS
M-400 that I have is just the plain "Starduster." I sucked at homework.

Do you think it'll actually perform better? Take it easy, Jay.
