Continuing the theme to get Foundation Licence
candidates interested in _REAL_ amateur radio,
which means, of course, homebrew and CW QSOs,
as well as the Pixie as a starter rig for only
a couple of pounds, we need to consider an
appropriately easy antenna for them, easy
to build, and, more importantly, easy to
erect.

I suggest two inductively loaded mobile whips
back to back as a dipole.

Any better suggestions, with the emphasis on
cheapness and ease? (Sorry Mr.Tarheel :-) )

Right then here's another one:-

Take a CB Radio DV27 mobile whip and affix two thick copper wires to the
top to form a "T" - the whip is now capacitively loaded. By lengthening
the whip as usual and moving the "top hat" in and out it is now possible
to resonate the antenna on several different bands.

what is wrong with a coax fed 7Mc/s dipole costing 10/6d ? ....

i'm off again to the trailer today be on 40m ssb on the way...then Belfast
tomorrow......

Just on that subject, you'll be arriving at the West Bank Road at 9:45?

Nothing at all apart from the difficulty for a beginner to
string it up.

I figured because he was talking about loaded whips, he didn't have space
for something bigger.

They may not provide great performance, but they do work to some extent.
There used to be a commercial antenna for small spaces that used a whip
and loading coil, hanging out the window. And the first ARRL Handbook I
got, in 1971, had a similar project in the antenna section.

I've gone a step further and fixed an electrical box as a multi-band
antenna in my attic. It was from a magazine article a few years ago.
Four pairs of mobile whips are mounted on the box, which has eight
surfaces around its periphery. All dipoles are connected in parallel to
a single feed line.

I used 80, 40, 20 and 15 Meter whips. Later, I changed the ground side
of the 20 Meter whip to a hustler with the multi-resonator adapter,
using both 20 and 10 Meter resonators. A short modified CB whip was
added to the top surface of the electrical box to provide a vertical 10
Meter radiator.

Such an antenna does not work very well compared to full-size dipoles,
but it gets you on the air. I'm not running a "Pixie" transmitter, but
a 100 Watt rig. I think a Pixie would still make contacts, but may be
frustrating for a beginner. Especially with the recent poor band
conditions.

I don't do 2m, call me when you arrive I'll be there waiting.
