Topband: Beverage on Ice

[Ron Feutz]

Topbanders,

Now that the river is frozen, I want to put out one or two Beverages on the 
ice.  I haven't been able to find reference material on this.

I will probably put down ~1000' to start.  Any advice on terminating 
resistance and method?  Short radial field, long single wire in same
direction as antenna wire?  Combination?  In case it makes any difference, 
the water depth averages about 12' in the direction I will start with.

How about feed point impedance?

Any references on this subject?

Tnks and 73,
