I don't have the antenna anymore since I have moved, but I believe it
was the Alpha Delta sloper. If not, it was a major brand purchased
from Universal Radio. It was NOT the longest sloper offered, but
rather the more compact sloper - probably more like 60 feet in length.
The antenna was installed properly and it was hooked up correctly.
Had the original Grundig connector, proper coax leadin, and like I
said, was installed by an experienced antenna installer.

Huh, don't know what to say other than I'm not an *experienced antenna
installer*(meaning I don't get nor have I, got paid to put up an antenna) but
mine has logged manyyyyy a stations for years. Interesting. Sorry about your
bad luck, and I really mean that Gary.
