I should have mentioned this is for 1.2Ghz and the feed to the DE is UT-141 Bob

Hello I am looking for some brain power from anyone who has built loop yagi's. I am getting my information from The ARRL Antenna book 20th edition. The book says follow exactly, however. It calls for alluminum elements 0.0325 thick, I have copper 0.025 thick. It calls for 3/4" alluminum boom I have 3/4 copper and some 1/2" stainless steel channel. The feed to the driven element is UT-14, I have a short piece with a SMA already attached, will connecting the SMA to a SMA-N adapter be acceptable? I have seen the pretty pictures of Directive Systems antennas http://www.directivesystems.com/loopyagi.htm Same idea only different parts. Are these things pretty "forgiving" or are the components critical? Also comparing the loop to a quagi the loop widths are 1/4" wide and the quagi used #18 wire, why? My intent is satellites and/or terrestial. Thanks for the bandwidth. 73 Bob W7LRD CN87 AMSAT 28498
