I used Directtive Systems model 2314LYRM 14 ELEMENT rear mount 36 INCH
15 dBi gain loop yagi for the past 2 field days. Feed it with 80 feet
of Andrews 1/2 inch hardline. I had a  6 foot jumper of RG8 from the
antenna to the hardline to do the twist. Also a 8 foot piece of the
same RG8 at the radio end as it just did not quit reach.

I tested this with the IC-1200 before the big day. I saw 23 watts at
the radio and 13 at the antenna using the Bird. Lord knows that is
enough to work AO-51 anytime.

Thanks W4AMC for the mode L/u contact. GD sig.
