Topband: Forestry Effect on Antennas and Radials

I have found a beverage in the woods especially in a suburban area are very problematic physically as someone always seems to wander across it and take it down.  I've since used bogs very successfully both physically and in performance altho I am certainly not prepared to compete in receiving quality with W8JI class systems.  In fact I. A suburban setting even if I could replicate the physical arrays the noise floor is quite self limiting anyway but even short bogs have allowed me to hear what would otherwise be totally impossible with other antennas here.

It does work, and slightly better than a K9AY loop oriented in the same direction.
