With the space limitations you describe, your best bet might be a 2-el
5-band quad...Take a look at GemQuad (fine Canadian product), and ask them
about ice loading. They're pretty tolerant.

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...

Thanks.)
