Wellbrook ALA1530+ Vs. ALA100?

Wellbrook Shielded?
I think it was Seein-I-Dawg who commented about the Wellbrook ALA-1530
being shielded.... As far as I can tell, having looked at their site several times, Wellbrook makes no such claims and points to the loop configuration as the reason why it rejects some near field RFI. This is also born out by the fact that they also sell an Indoor version of the antenna which is packaged in a sort of plastic hula hoop, rather than in Aluminum tubing. Wellbrook does make a very nice preamp and I suspect that the ALA-100 WILL outperform the ALA-1530 and the ALA-330s with 50 feet of wire on it. (I currently have an ALA-1530 and hope to have an ALA-100 shortly so I'll let you know.)

It's a pity these sorts of locations are so few and far between. In most locations, atmospheric noise is significant *all by itself*. The Wellbrook loops are not shielded. The exposed metal is the loop. The 1530+ high bandwidth version looks ineresting. You could justify the cost if you use it for FM broadcast. Otherwise, get the ALA 100 and roll your own loop. |

Well, judging from my ALA1530, which I have partially disassembled,
there is wire running inside the Aluminum so the aluminum is not the loop. The indoor version doesn't have any aluminum on it either as far as I can tell, just a plastic outer covering.

Wellbrook Shielded? Nope!
Actually,
I do know what is inside the plastic loop. If you search on Wellbrook and look at some of the past topics about it, there is one where someone was asking the shortwave shop (their distributor) about the indoor plastic loop, and the guy from the shortwave shop replied that it was flexible and just had wire inside of it, so it could be squished through narrow openings to the attic, I assume.

Rob This question keeps popping up on this newsgroup. Wellbrooks are not shielded. I still like the ALA100 because you can roll your own antenna.
