Subject: [loopantennas] Wellbrook ALA1530
Fairly recently, I purchased a Wellbrook ALA1530 loop antenna to
hopefully enhance my HF listening. Earlier this morning, I decided to
do a bit of experimenting and, out of sheer curiosity, hooked my my
VHF/UHF scanner to the Wellbrook. To my complete surprise, the aero
frequencies I have programmed into the scanner came in with cleaner
and in some cases *stronger* signal than the Diamond discone I
normally use for scanning!
The Wellbrook is 'ground mounted' i.e. approx. 6 feet above ground and
approx. 20 feet away from the house. The Diamond discone (specifically
designed for VHF/UHF) is mounted on the roof of the house and approx.
20 feet above ground.
VHF Coastguard also comes in on the Wellbrook with at least equal
strength to the discone... and I'm approx. 15 miles away from the coast.
Has anyone else had this kind of experience with the Wellbrooks?
