http://www.rogerhalstead.com/ham_files/cablebox.htm. Heaving due to
frost has never been a problem. Codes do not apply as there is no power
other than the low voltage to the rotator.
In general, technically not true, unless your local authority has
exempted it. Rotators are typically Class 2 low voltage, but there's
plenty of electrical code to cover that.<grin>
Locally, permits are not
required for ham towers and stations. Code does apply to electrical
circuits with permits required for new circuits, both 120 and 240 which
IIRC $25 for each breaker installed and must be inspected.
