Antennas for 6m Es

One of the amazing things about the Magic Band (6m) is that for Es (sporadic-E) propagation, and I suspect for F-layer, almost any antenna will work. For years I have used just a V2000 VHF triband vertical with excellent results including the USA, Azores, North Africa, Ukraine and Israel worked with low power SSB/CW or spotted on  WSPR.  Polarisation often gets twisted so a beam is NOT needed.Yes, for tropo DXing a horizontal beam might well help but many GDX paths involve aircraft reflection where polarisation is also twisted.

A simple half wave vertical for 6m is at http://users.belgacom.net/hamradio/schemas/on6mu_6meter_verticalantenna.htm .

Hi Roger,

Although polarisation twisting certainly does occur. You may find that the V-2000 (and other similar antennas) with one tuned radial on 6m provide some degree of horizontal polarisation in certain directions.

Of course that is true Martin. My point is that with Es the polarisation is of little consequence if signals are randomly twisted over the path.
