[ILQSO] antennas for ILQP

Paul,
Last year there was some a similar discussion on the Society of Midwest Contesters reflector. Someone sent me a summary of an article that had been published in the National Contest Journal. In the article they had modeled the best antenna for close-in contacts. I will need to find the e-mail to get all the details, but for 40 meters the "perfect" antenna is a dipole at 50 feet, with reflectors 5% longer than the dipole, strung up at a height of 5 feet and placed 5 feet out from the dipole. These reflectors aid in high angle radiation. For the 2006 ILQSO I implimented some of these ideas. My dipole was only about 40 feet, and I used only one reflector, laid on the ground under the antenna. In side-by-side tests with a vertical it was about 10 Db better than a vertical for in-state contacts. Imagine what it would have been had I properly elevated it and used 2 elevated reflectors. It was about equal to the vertical on DX. I should have used that antenna again this year, as my 2006 score was double that of this years effort.
