ANTENNA TIPS
(FASTENERS)
. A dress maker's straight pin poked through the hollow section fuel
tubing so that the ball end fills up the I.D. of the tubing .Insert the antenna wire
started through the fuel tubing and there will be enough friction to keep the wire from
pulling out. Now, simply stick the pin into the top of the fin, or the side of the
fuselage and pull the antenna taunt. The antenna will stay where you put it, but will move
without breaking in the event of a large bump to the airframe.
(INSTALLATION))
Never exit the receiver antenna wire to the exterior of the fuselage by running it
out via the wing saddle, or anywhere near the wing-fuselage joint. The vibration and
relative movement between the two during flight will eventually sever the antenna wire.
The proper method is to punch an exit hole in the fuselage, near the receiver location and
away from exhaust residue. Obtain from any electronic store heavy
sleeving material of the
size that will allow the antenna to slide through. CA about a three inch piece of this
sleeving in the antenna hole such that about a 1/2" or so is inside the fuselage.
Pass the antenna wire through the sleeving and attach to the rear of the fuselage .
However, before you pass the wire through the fuselage, put a strain relief on the wire
inside the fuselage to prevent it from being pulled out of the receiver. The best and
cheapest strain relief is either a button or a broken off portion of a servo output arm.
Simply weave the wire through the holes in the button or servo arm about three times and
its done. Make sure you position the strain relief on the antenna wire such that there is
some slack antenna inside the fuselage when all is done.
( USAGES)
Do not throw away broken Tx aerials. They are a good source of thin brass tubes
which are very useful for bushes, small pushrods, tubing, guides, etc.
Here's a few more hints on Securing the antenna wire
.Use heat shrink tubing the size that
just fits over the antenna wire (usually 22 ga wire). Heat the heat shrink tubing on to
about the last inch or so of the antenna wire, leaving about three inches of the heat
shrink extending beyond the antenna wire itself.
You can then tie as many knots as you want in the heat shrink . Also The inner tubing of
most flexible control rod (i.e NYROD, Goldenrod, etc.) makes a great fastening point for
the receiver antenna. Glue a short piece (1/2" or so) to an appropriate place on the
aft section of the fuselage (vertical or horizontal stab, fuselage side, etc). Run your
antenna wire through the piece of tubing. Then wrap the antenna wire on the downstream
side of the tube with just enough masking tape to prevent it from easily pulling back
though the tube.

Note: Although the frequency list for
the 53Mhz portion of the 6 Meter band is correct, the governing body for this group of
frequencies, The American Radio Relay League, has dropped the 53 MHz portion for R/C use
as there are hi powered repeaters operating in that portion of the band. It would be
advisable if you are a Ham radio operator to use the 50MHz frequencies for R/C . They
recommended migrating to 50Mhz about 5 years ago and no longer list 53 MHz in the band
plan.
