RECOVERY

NOTE

When preparing to recover the antenna wire elements,

unclip them from the balun and clip them to the mast,

or a stake, so you have something to give you tension

to pull or roll against. Preparation for movement is the

exact reverse sequence of erection. Lower the balun

slowly, because there is a heavy mass of wires, coax,

etc. If time permits, they should be let down some,

and then pulled away some more. The wire sequence of

rollup is 4 -3, 4 -3, 2-1 on each of the reels.

NOTE

The halyard and weak link can be rolled right over the

top of the wires on one of the antenna element spools.

PERFORM AFTER A LIGHTNING STRIKE

The following steps are necessary to ensure that the radio, transmission line, and antenna are in

operable condition after a lightning strike.

1. Make a continuity check of the lightning arrestor using an ohmmeter set to the highest range: (a) From

the shell to the center conductor of each side of the arrestor - Open Circuit. (b) From the center of one to

the center of the other connector - Open Circuit.

2. The next step is to test the radiating elements of the antenna.

3. Lower the Balun and disconnect the radiating elements from one side.
