Re: [HCDX] Wellbrook ALA1530 setup
Hi Deano, the Wellbrook 330/1530 loop is 1m in diameter but there is an LF
version of the wellbrook that uses a large aperture wire (I think about 25m)
There are different models of the smaller Wellbrook loops - I don't know
which you have but they cover different frequency ranges. The one I have,
the ALA330s covers to approx 100MHz (gain is a bit low at the top end) so
could probably be used for ACARS, although I would think a pair of crossed
dipoles would be better for this as they would be omni-directional. The loop
does does become very directional at VHF so a rotor of some kind would be
very useful. I would recommend a visit to the Wellbrook website: http://www
wellbrook.uk.com/ and if that doesn't answer your questions, then email Andy
Ikin (sales@xxxxxxxxxxxxx). As for the 2001d, lovely radio - I used one for
many years, the only thing you may find is that the Wellbrook loop has too
much gain for it and may overload it on certain frequencies (I think the
2001d is a little prone to this especially on FM/Airband if I remember
correctly). Hope this helps a bit!

Subject: [HCDX] Wellbrook ALA1530 setup
I have had my sony 2001D ser no. 321396 since new and have not really taken
advantage of it by setting up a decent antenna. I have been given by a
friend his Wellbrook active magnetic loop antenna unit & interface unit but
no actual aluminum antenna. He was using a single flexible wire loop but I
dont know what size.
Can someone recommend a suitable single wire size for me to use and what
would be the ideal diameter of the loop using a flexible wire?
When setup I would also like to use the radio to recieve weatherfax, would
this antenna give a good reception for this? Also does it increase the
reception of VHF so I can setup to recieve aircraft ACARS info?
Hope not too many questions at once but many thanks for any replies,
Deano
