It's just bliss to have that phenomena that Guy describes: when
the noise on the antenna's is so low you start checking to see if
in fact they are connected. It is such a joy to hear stations
thousand's of miles away waft in over the airwaves as clear as a
bell, yet the signal strength is so low it doesn't even move your
"S" meter. What a thrill!


It's a pity these sorts of locations are so few and far between. In
most locations, atmospheric noise is significant *all by itself*.

I think it was Seein-I-Dawg who commented about the Wellbrook ALA-1530
being shielded....

That was a mistake. That Troll usually posts off topic political crap.

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.

The loop configuration is a reason that the antenna design will be
helpful in reducing local interference.

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.

You and I both do not know what is inside the plastic tubing. It might
be shielded or it may not.

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.)

Externally the antenna design is good way to go but it would depend on
how it was executed.
