[Antennas] unusual question but....

[David]

Hi Bill, Happy Wednesday!

Those pipe warmers are UL aren't they? Dangerous? Please elaborate.

I use a small 120VAC light bulb in a small metal cabinet that has things I
don't want frozen and/or sluggish. Actually, I use two bulbs, just in case
one burns out and it is cold before I notice the burned-out bulb.

Maybe it is too far to run an extension cord or whatever...but what powers
the rotor?

Hmmmm.... Use the power for the rotor to power a heater or light bulb.
Maybe there could be a switch/relay to cut the bulbs out and power the
rotor whenever the rotor is needed if the current supply is small.

** Chicagoan, I live a few miles from Ohare Field.
** We have had one of the worst winters in a long time.
** While this is a recently 'checked out & serviced' rotor, it's really
** having a tough time turning my old Wilson Crank up tower.
** Slow and sometimes a tad slow to start turning. Once it's gets going and
** turning it's better, just those first attempts in the morning.
** It is a new cap in the control box. I always keep a spare.
**
** Has anyone come up with a good way to keep them warm?
** As you know, the rotor is at the base of the tower and turns the whole
** tubular tower. Sort there is some bit of resistant torgue at the start.
** I bought one of those small plastic storage bins, carefully cut it so
** that it fit around the rotor portion and the bearings.
** Just to keep the frozen snow off of the rotor. (I do mean frozen as we
** then had a day of freezing rain that put a crust of HARD snow over
** everything.
**
** We are back down to near zero again and expecting more.
** Too late for this winter but has anyone ever come up with some sort of
** way to keep a rotor warm. Those electric water pipe thawing gizmos seem
** dangerous.
** Anybody???
