I have received another stack of comments on gin poles, plus
an even bigger stack of requests for information.  As a seeker of
information myself at this stage, I am afraid I have no way to
satisfy some of the requests.  But I will tell what I know.

My e-mail on this subject falls into two categories:  (1) further
comment on the respective merits of the various designs, and (2)
requests for addresses and telephone numbers of suppliers, and 
pricing information.

Some interesting comments on the merits:

1.      More guys have praised the WB0W product.  There was,
        however, one negative comment.  Evidently, the WB0W
        design requires a counterclockwise rotation of the
        locking knobs to tighten the pole bracket to the tower
        leg, and to position the pole within the bracket.  One
        user found this to be a constant annoyance, given that it
        is conventional for a counterclockwise rotation to 
        *loosen* rather than *tighten* a knob.

        He liked the Rohn poles because their loosening-tightening
        process follows the normal rotation.  But he admitted that
        the EF2545 (for 25G and 45G) is not very hefty in construction.

2.      As to the Antenna Mart pole, I received the following:

        I've thought about this just a bit.  Perhaps the rungs
are strong enough to support the *vertical* weight involved.
Sometimes, though, I use a gin pole for horizontal (or nearly
horizontal) loads, such as with a trolley system for elevating
yagis.  I am particularly reticent to apply force to Rohn
cross braces in a horizontal vector, even if the braces could
safely support a dead vertical lift.  Just a thought.

Now some info on addresses, pricing, and the like:

1.      IIX Equipment Ltd.
        P.O. Box 9

        $189.95 for a kit that includes gin pole head
        and mounting bracket only.  (pole itself is 
        not supplied)
