The variable tuned SteppIR is pretty much all fiberglass or plastic on
the outside, so it might also be durable in hostile environments.
Give me a call in about twenty years and I will report on it. My SteppIR
is 122 feet from saltwater, so it has some corrosion to deal with. Put
it up Dec 1, 2001. So far so good.

A couple of more observations. There was a company who will be
introducing titanium yagis. Their claim is that the antennas will not
corrode
and they will be practically indestructible. For those guys with hostile
environments, they may be worth the additional 30-50% cost factor. We'll
have
to see what designs they come out with. I don't know if they'll make the
titanium itself available.
The new AlfaSpid rotator was on display. It's a smallish rotator but
does
have the worm gear drive that should be a great feature for any
installation.
The rotation is controlled either by a dedicated mouse with preset
buttons on
the side or push buttons on a small profile control box. I'm not sure of
the
specs but this should be somewhere in the T2X/G-2800 range. Don, VE6JY,
says
he's turning a full-sized 40M beam with one.
The AlfaSpid is a rotator that's been out in EU for awhile so there
is
already some sort of track record for it (any feedback out there?). It's
made
in Poland and has 8 bolts through a tube for both the mast clamp and the
base
mount. The bottom of the base mount has a flange that can be plate
mounted so
it can either be plate or mast mounted. The Dayton special price of $535
is
very attractive but I don't know if they have a 'normal' price for it
yet.
The interesting story here is that there was a radio store in
Edmonton
(I'm sure the only one) where these guys are from that was going out of
business so 20 of the local hams got together and bought it to keep it
going.
This rotator is a product of their own. How many guys are willing to put
their money where their mouth is?
Cheers,
