I have received a very strong response to my question regarding how close to
my house foundation I can safely put my tower. I wish to thank all that
responded, and thought others might like to see a summary of the responses. I
hope this doesn't push the reflector charter too far.... The summary follows:
TOWER BASE/FOUNDATION SUMMARY
concern might be if the ground under the foundation/slab falls into the
hole, yet if you fill the whole thing up with concrete (including the
void under the slab) there should be no problem.
Several years ago (at a previous house) I installed a self-supporting
tower with full building permits and inspections in Cupertino
California. The concrete of the base touched the concrete of the
house foundation. That house also has no basement.
I had a W-51 tower up and had its base about 3.5 feet from the
basement wall..
I have a US Tower HDX-589 on a 4 x 4 x 9 foot base that is just about
as close to my house and it can get. The edge of the tower clears the
eave of the house by about 12 inches. The base is within 6 inches of
the house foundation. City of Los Angeles inspector had no problem
with it (and they are usually fussy). Put it as close as you need to.
Contractors dug an 8'6" deep hole 4x4' square
about 36" from my foundation. I told them to be prepared to shore it up
with 4x8 sheets of plywood and braces, but it clearly wasn't necessary.
It is something to be concerned about, though.
i put my lm470d about ten feet from the house. i think i
could have gotten as close as 3-5ft without getting nervous.
END OF SUMMARY

I have an itch to do the June VHF contest from the Bahamas. Does
anyone on the net have a suggestion of a place that tolerates hams,
especially in contest-mode? Maybe even a rent-a-contest-QTH spot?
Thanks - Michael Owen

Yes. There are a lot of them. When I get back into the office, I plan
to finish compiling a list. Below is a list of the ones I have so far ...

I asked Billy Lunt at ARRL that question last week. He is behind (I believe
he was working on SS article for QST). I got my receipt for ARRL CW
yesterday (about 2 weeks after I sent it in). I have not received one for
Phone yet. Usually it only takes a day or two. Get worried a few days
before the submission deadline.

Subject: antenna design
Message-ID: <2D80F435@admin.ClemsonSC.NCR.COM>
It shouldn't be a big deal...buy the rotatable dipole from
cushcraft and the extra aluminum tubing from Texas Towers
or Metal and Cable. I've thought about this myself, and thought
I would model it after the dimensions of the Hygain 3 element.
I think it has a 36 foot boom. I'd just shorten the driven element
by as much as the director is shorter than the reflector, and
then run some computer models to make sure I hadn't
totally screwed it up.
However, for all this cost and trouble I don't think the 2 to 3
db of forward gain is worth it. I have missed NOTHING on
40 meters with my 40-2cd at 80 feet, including VU, HS, JT,
8Q, VQ9, 9V, S21 etc, in the log. Matter of fact, I'd rather
spend the money for more tower to put a second beam at
150 ft than to add a third element ('cause I don't think the
2-3 dB from the third element will be worth it unless you
critically optimize it to improve Front to Back, and then you'd
probably lose the great 2:1 SWR bandwidth of this antenna).
I am, however, a Cushcraft 40-2CD zealot. I am not
crazy about their other antennas, but this one is superb.

PS: Yes, OF COURSE, if I had the money I'd put up stacked
DX engineering 3 over 3 full-sized yagis on 40. I must,
however, deal with my current fiscal reality.....

does anyone know of a design that converts a cushcraft 40-2cd to 3 elements?
