TE-AEA
Amateur HF Emergency and
Portable Antenna.
Pic. 1.
This portable emergency antenna is primarily designed to be used either when your mobile antenna has failed and you
need an emergency back up, or if you just want some more portable fun with a more efficient antenna than your mo-
bile antenna. It can be used in a variety of ways, and although it may not be a perfect resonance on every band, when
used properly it will still be in the ballpark and allow your transmitter to work and get a signal out. In conjunction with
a tuner it can be quite efficient. Without a tuner it is designed for the 80,40,30 and 20 metre bands.
To best use it, the ideal scenario would be to park about 22 metres from a branch that you know you could throw a
stone or stick over. Or you might have another throwing device in mind.
In an emergency, if there are no trees around or your car is not mobile, the next best thing is to lay it over some
bushes. As a last resort it can be laid on the ground, the drier and sandier (up over a sand hill) the better.
Instructions.
As an emergency antenna, for 80,40,30 and 20m.
1.
Unclip the bulldog clip and unwind the 1 metre long earth wire up to the plastic joiner with the
coaxial connector.
2.
Disconnect the coaxial cable from
your mobile antenna and screw it onto
the emergency antenna.
3.
Wrap the earth wire around some fit-
ting (bullbar, ect a few times to take
the strain of the antenna, as in Pic.1.
Then clip the bulldog clip on to some
earthing point i.e the bottom of your
mobile antenna or its earth strap.
Do
it in such a way as to not put pres-
sure on your coaxial cable and fit-
ting, as you risk separating the
coax and the connector.
4.
Unwind the antenna from the winder in the direction you need to go to be able to throw it over a
branch . You will notice that the antenna has small pieces of heat shrink with the bands on them
at points along the antenna.
5.
Roll it out until you get to the band you want to use and then hook it around the winder hook as
in Pic.2. or Pic.3, depending on which end it is near. It will be close to the resonance that you
want to use, but you can check and improve it with the use of an SWR meter. Anywhere around
the frequency will be OK, but set it short rather than long, you do not need to duplicate the pic-
ture exactly.
