Prevention's the best medicine when it comes to unsticking whip antenna
sections.
KEEP 'EM CLEAN: BefOre putting sections together, be sure they're clean.
Grit or dust on a ±ating surface can Jock the sections up tight.
A pencil eraser, notebook paper or a non-abr²sive pot scrub
?
er will do the
cleaning trick. Lay oF with steel wool, sandpaper or other abrasIves, tho. They
take oF the copper coating the sections need fOr good electrical contact.
You can use a bore brush³gently´
to clean the µmale mating sections.
GREAS¶ THE SK·DS: ¸nce they're
clean,
add a little silicone,

Don't overdo the lube on radiat¼
ing antenna sections. Use just enough
to smooth the way, and keep 'em ½om
fr»ezing together. To keep sections
f¾om sticking, back 'em oF half a turn
afte¿ you've snugged 'em up.

Prevent sections f¾om binding by taking 'em apart oc¼
casionally. Experience will tell you how often it's needed.
·f you already have ½ozen sections on your sturdy tubular Àntennas, h»re's
one way to g»t 'em apart. We heard
about it ½om thÁn SSG Robert Bonura
of Ât Polk, LA.
Tie a tent peg to each end of a 5-ft
rope. With a buddy holding one peg,
wrap the rop» around the sections
counteÃclockÄise. SÅrt Æ8 inches above
the ½ozen joint and end Æ8 inches
below it.

With your partner holding his end still, turn the other end around the sections
until the rope tightens. Continue until the section loosens and begins to tÇrn.
Take it apart by hand if you can. ·f you can't, do the "rope tricÈÉ again.
·f a bottom section binds, wrap the rope to the antenna base. Êold it there
while your buddy turns the top peg.
