Topband: Loaded BOG Rx Antenna - 160 meters

[Chris Zeal]

Hi all

Thanks for the replies below from Bob and Eric to my mail of 8 March.

What do you expect that lumped inductance in the middle of the wire (or anywhere else, for that matter) to accomplish? I can't see anything in the theory of that antenna, which is somewhat limited, that hints at this.

What is the purpose of the loading?  Slowing the signal on the wire is not helpful.
Termination value changes with weather conditions, ground characteristics. 
200 ohms is a fair average value (for resistor itself). 20 ohms is certainly too low unless the ground connection itself is in the range of 200

Both points are noted and appreciated.  I am not in a position to argue technically.  However my aim was to compensate for the shortened length of BOG while accepting additional signal loss.  If loading is not worthwhile where does this leave the 'slinky' type system?

Incidentally the ground here is very poor and probably does account for the high resistance earth connection.  I am feeding via a 1:9 transformer (I tried a 1:4 first).

I shall carry on with the experimentation.
