Topband: Receiving loops

[James Rodenkirch]

Tim: I laid down a Dipole On Ground (DOG antenna) - it ended up at just right at 150' (two 75' sections) as indicated by an MFJ-259 analyzer I used that says it's spot on at 1.2:1! Compared to my 43' vertical, noise levels are down at least 2 S units - something to consider, when space is limited. 72, Jim Rodenkirch K9JWV

> I want to try a new receiving antenna for the summer Stew Perry. Last winter was my first foray onto 160M and I really felt like an alligator. I could work everyone I could hear, with just 100W. I think that means I need a better receive antenna. If you look at my score in the winter Stew Perry I think I did great QSO-number wise, but my average distance was very poor, I'm guessing typical alligator.

Compared to my transmitting antenna (A "T" with a poor radial system) most signals were still better, S/N wise, on my transmitting antenna. I feel like I must've been doing something wrong. Still the fact that a few signals came in on the loop with by ear much better S/N, maybe I was on the right track and just didn't try hard enough.

And maybe a terminated beverage but I'm limited to about 150'... well maybe I could run something longer down the driveway as long as I clean it up before the sun comes up and the neighbors see.
