>> The problems I have are finding a braided rope. I don't want the type
>> that has the woven protective sleeve over it. I have problems with the
>> core sticking out through the jacket with that stuff. I purchased a
>> 1000' spool of 3/16 braided that is something like 800# test, must be UV
>> resistant as the stuff that has been up holding antennas for 3 or 4
>> years is just as flexible as it was when I put it up...and no noticeable
>> stretch...AND inexpensive, or it was when I purchased it. The stuff is
>> great for general purpose work and I had a 500 foot roll of 1/2" braided
>> that has been great. They may not have quite the strength of the double
>> braid (core with cover), but I find them more durable.
>> I'm pretty sure I purchased it from either The Wireman, RFParts, or
>> Davis. I don't think either came from Davis. The problem is when I look
>> at the sites, they don't give a complete description. Guess it's time
>> to get on the phone. All three places have been easy to deal with and
>> very helpful. As I've mentioned before, I'm sticking with Davis
>> BuryFlex(TM) for my rotator loops.
>> I've reached the point where I need another spool of the dark OD or
>> Green 3/16" (No it's not parachute cord) and another 500' of the 1/2".
>> Now if I could just find out where I purchased them<sigh>
>>> -- light weight 8 foot fiberglass rod or tube, at least 1 and half inch
>> 1 1/2" diameter rod would not be light so you are looking at tube.
>> I gave away "the remnants" of a Diamond 144/440 21' tall vertical that
>> had been "shortened" by lightening. About a foot from the top it looked
>> like an exploded cigar and the radiator looked like a used piece of
>> brazing rod, but the rest of the jacket was good. Matching network was
>> also shot. But at-any-rate, the bottom section is about 1 to maybe 1
>> 1/4" tube that would be long enough, although I don't know if it'd be
>> strong enough. So, you might also look for some of the old Diamond and
>> other antennas of that type as I'd bet quite a few get thrown out. You
>> can fix the radiator easily enough, but I don't know how to fix the
>> matching network which is potted. Any way it might be worth a try.

>>> Well, my quad broke today in a gale. The wind estimater says speed was
>>> 50 to 56 mph based on small tree blown over, twigs and limbs down, and
>>> on. I am impressed that the grass in the lots beside and behind me ...
>>> grass about 2 ft tall, was blown completely flat, so he wind at actual
>>> ground level was bad, too. Standard factory Cubex with factory
>>> stiffner... 2 el full size 40m, 2el on 30, and 3 el on other two WARC
>>> bands. Really worked nice!
>>> I made the mistake of not heading my quad West where the wind always
>>> comes from... I think because it hit it on an angle, one of the top two
>>> spreaders broke at about the half way point and all the wires of the
>>> driven element are drooping over the mess that is left. The reflector,
>>> lacking he added load of the driven coax attached, survived. I think
>>> driven array also rotated on the boom and the whole thing could have
>>> pushed back on the mast, it appears.
>>> I had plans already of putting in 8ft extensions on the ends of the boom
>>> and tying the whole thing into a fully guyed internally. I do not know
>>> how I can get another fiberglass spreader shipped here, it is very long,
>>> and I have only one fiberglass extension rod to do the strengthening so
>>> that is another part to find.
>>> If you have suggestions on a very light very strong, sun resistant, non
>>> absorbing string, line, rope.... please let me know. de HS0ZCW
