Lance , thanks for the qso today. In looking into my file I guess I did not
send the request for the info update on the 6M2WLC antenna. It is a boom
length of 39.5 ft and carries 9 elements. I would like to see some
comparisons with other "biggies" before I assemble and install at the new
qth in CM95 Nipomo,ca. I am unable open the .ant file with this original
email. What do I need for this? Mike Goshay w6we
