Hi Roger,
Indeed, I know the spiderbeam since the very beginning but it is really too
huge I believe
I list all "portable" multibands solution in this excel file
http://www.astrosurf.org/lombry/qsl-portable3.htm
From what I have seen or read, most portable beam are working on 6m or
below.
Remain the quad that works fine closer to the ground than the beam.
Hard to find.

Hi,
I need your advice. Here are my needs :
I'd like to DXing on portable at 100W SSB. I am looking for a directive
antenna displaying an interesting gain and F/B. Another factor to
consider
is the price but I am not ready to build the antenna myself. The
rotation
of
the mast/antenna will be insured manually.
I have thus to use the lightest 2-ele quad or a 3-ele beam.
My weight being close to 65 kg the weight of this antenna should be of
20
kg
max (at first sight. I don't exactly know what weight I canb lift up,
but
probably not much)
If this is a quad I think that I can still place it 3-5m high max (the
lower
string being 1 to 2m over ground), for sure much higher for the beam.
The overall length of the antenna cannot exceed 4-5m and the possible
boom
must be telescopic or easy to assemble as all parts could enter in a
medium
size car (so elements to assemble must be 2.5m long max or so)
So I am looking for a dealer manufacturering light elements or
collapsible
antennas or easy to setup (in less than 30 min-1h)
At last I prefer a full length quad or, if that exists, a quad using
traps
(but I've never seen that) but the beam could use traps and the ends.
This antenna must be tuned on 20m or maybe a tri-bander 20-15-10 or
20-17-15m
Is this a dream or not ? If not, do you know some manufacturers
providing
such antennas ?
Excepted Hexa-Beam Light models, I don't really know other dealers (and
BBQ
is a shortened quad and quite heavy and Titanex sells only large beams
and
verticals).
Do you have some good experience in the field in erecting such /P beams
?.
If you do, what model do (did) you use ?
Thanks for your comments

Spiderbeam - 3 or 5 bands - 20 to 10m
www.spiderbeam.net
Easy to build, cheap, good performance, very light weight and packs up
compact.
