I've now had mine up a few weeks and made a few contacts (nothing over 1,000 miles).
Scratch that. I just made 1,900 miles as 20m was closing for the day.
The antenna is mounted East-West with the West end at 15' and the East end at 10', with a mobile home 15' away on the South and 25' on the North. TenTec HB1B pushing about 5 watts into 50' of RG8.
Thanx to all who suggested this antenna; it's a winner.
