Okay here's the deal,

I would absolutely love to put up a Log P, but lamentably my tower is only
42' to the thrust bearing, and if I put up even the smallest Tennadyne T-6,
the 38' (2x19') rear element would severely overhang not only the neighbors
yard, but their house as well. (they are 24" from the lot line.)

My other concern is ice. That is to say, when it ices up (as it will
inevitably do several times each winter) the longer elements could droop to
the point where they could strike his roof, mine, a nearby tree. (heck, the
balance between peace among neighbors and a decent antenna system sure is
frustrating...

So, I have to keep it small, but I would like it to cover more than the
usual 20-15-10 devices, and still have some level of performance. (gee,
while I'm at it, let's have it defy gravity, be completely invisible, and
guarantee a 59 copy to even the remotest corners of the globe... but
seriously folks, I need some real life testimonials here!)

I have a brand new TH3JR (purchased 5 years ago) still in the unopened box,
but I'm thinking 'more bands' would be nice.

I found a local place that has some interesting antennas, but I find few
references to them and their performance on the web. (that's not to suggest
they are not good devices, heck, they could be a well kept secret little
gem.) Here's a link to the one I'm looking at:

http://www3.sympatico.ca/tgmc/mq-2.html

It's quite compact, and a very different configuration from anything I've
seen elsewhere.

So, what's out there that's small and yet delivers decent performance with
20-17-15-12-10 in mind?

Any helpful firsthand experience passed along would be very much
appreciated!

A log periodic is similar to a discone in that the shining attribute is
wideband coverage, not gain. If you look at the gain curves, and F/B, you will
see why the manufacturers often quote maximum gain, not average gain, and I've
never seen a gain or F/B ratio plot as a function of frequency in their ads.
As long as you know what you're getting, you won't be disappointed.

How about the StepIR rotatable dipole, or their two element beam?? A
little pricey,
but it works.

Pat,
If I were you, I think I'd forget about a log-P antenna.
Personally, I'd forget about the locally made one too. If
the 'TH3JR' is still in the unopened box, it sounds like you
don't really care much about having a beam up in the air and
in use. And to be painfully honest, it also sounds like you
just don't have the room for one. Keep shopping for that
gravity defying, invisible, super-duper special only 3 feet
wide with the built in de-icer...
'Doc

If small with gain on 20-10 including the WARC bands is the goal, I'd
suggest looking at the Hexbeam. Quite pricy compared to the TGM you
mentioned, though. I'm quite happy with my 5-band Hex, for what it's worth,
and it's turning radius is 10 feet (even smaller in metric)

Why not move? With the current sunspot situation you will have five
or more years before anything above 20 meters is useful so you will
have plenty of time to find a new QTH.

Hi,

Hexbeam is light, great for portable or small space but it has to be modify
manually to work on other bands...
Not the best way.

You can get a Titanex beam, better, lighter, cheaper...

Sorry, but you are misinformed. The HX-5B hexbeam meets all the
requirements that were stated. There are no "modifications" required to
operate on the 5 bands. You obviously do not own one - I do.

Doc,

I hear you loud and clear, I know it's tight up there, and with Rocky &
Bullwinkle guarding the upsiedasium, there won't be any invisible Al-Ti-Up
alloys anytime soon...

But seriously, I know it's limited, and I knew that when I put the tower up
a month ago. It was the only place in the yard available. (big pool, two
decks, hot-tub, pool-shed, and oodles of beautiful trees... again,
everything is a trade off with suburban living.)

I have read Log-Ps are not the be-all end-all antenna, but are good
solutions when you want 'one' multipurpose antenna with some steerable
directivity and an assortment of bands. And yes, any specialised monobander
will outperform most multipurpose devices. (what was that we were saying
about trade-offs??? Darn near everywhere aren't they?)

So, with all that said, I'm looking for the best compromise. The house next
door is 12 feet from the centre of the tower, so if I can keep the turning
radius around 15', at the 42' height, it won't look to bad at all, AND I can
park the beam pointed either directly toward, or directly away from the
building. That way, with a total boom length under 18 feet, it will be
entirely in 'my' airspace when not in use.

So the search continues for a something with a 18' or shorter boom, with a
longest element no greater than 30', and won't droop too much with moderate
ice loading. I know the 'droop' of an element is a non-linear function based
on its length and the total ice load, but from a practical standpoint, on
the longest element, how far down will it bow? I'm guessing if I paint the
topside of the elements flat-black it will help with shedding the ice when
the sun hits them.

Thanks again for sharing the wisdom of the group...

Pat, VE3PMK
(please respond here as I am slowly getting the spambots under control.
Thanks.)

I used the TGM for three years and really liked it. It is a great little
antenna. There are 27 reviews on eHam - all give this little beauty a
perfect "5" rating. Look for "TGM Communications Hybrid Quad." I would
highly recommend it.
