Looking for a site or information on incoming
radiation angles specifically for 160 metres.

1 How is it measured ?
1a Can it discriminate between vertical and horizontal
or what ever polarisation

2 What is the angles per percentage of contacts

3 Are they all horizontally polarised when subject to skip?
for distances over say 1000 miles distance

One well known DXer (Tom) stated on this
newsgroup that a horizontal dipole at 1/2 wave
length was inferior to his other antennas, but
no specifics given!

Appreciate any pointers on the above.
Happy New Year
