Speaking of heaters, I used to be in the land mobile VHF/UHF repeater
service business.

The repeaters inside the buildings were no problem because the other
equipment in the building kept things warm. However, the outdoor pole
mounted boxes were a problem. In particular, the large duplexer
cavities required some form of heating or water would condense inside
and detune the cavities.

So, I went to the local pet supply dealer and bought some doggy
blanket heaters. These are miniature electric blankets but sized for
a dawg. Wrap the cavity with the blanket and it stays nice and warm.
I also tried a 40 watt light bulb and a mercury thermostat plus relay.
That also worked but tended to heat the metal box more than cavities
and was therefore rather inefficient. The doggy blanket heaters put
the heat where it was needed.

A bird bath heater might be cheaper, but I needed something that would
evenly heat a surface and the dawg blanket heater was ideal.

I doubt anyone needs as much power as a doggy blanket heater offers
for keeping a comparatively small WRT54G router warm. Probably a few
power resistors and a bimetallic thermostat will be sufficient to
prevent condensation. Whatever you do, do NOT mount the board
horizontally where the water can collect and puddle on the board.
Mount it vertically where it can drip off. Also, give the water a
place to go (details on request).
