[TowerTalk] Sloper on 40m?

[Jeffrey Demers]

I have a 50' fiberglass mast with some VHF antennas on it.  I'm planning to take the VHF stuff down and re-purpose the mast for HF.  I'd like to try and make some improvements on 40m to EU (Right now, I use a 1/4 wave vertical with several hundred radials) - and a sloper seems viable to get some gain and directivity.  (So far, so good...or am I wrong already:))

The basics seem straight forward:

-A dipole sloping at 45 degrees from the mast pointed to EU.
-The coax coming into the center feed point at a 90 degree angle

If I'm reading everything right - the mast must become a parasitic reflector and some wire introduced to it.  How long, what diameter should the wire be? I'm also curious if anyone else is using a similar arrangement?

Feedback appreciated.  Thanks in advance

Thanks,
