Based on Guy’s EZNEC modeling I’ve decided to get a FLG100LN-2 instead of the ALA100LN. I already have a flag constructed, and it’s mounted alongside my wooden privacy fence to favor the Western US. Since “K” calls from the West are my primary interest, it makes sense to keep a uni-directional antenna, instead of converting it to bi-directional—especially since it seems it would be easy to make it bi-directional should the need arise in the future.
Can’t wait to try it. 73, Les Rayburn, director High Noon Media Services 130 1st Avenue West Alabaster, AL 35007-8536 205-621-7500 205-621-7505 FAX 205-253-4867 CELL highnoonfilm.com [This message and any attached documents contain information from the sender that may be confidential and/or privileged.
