I received enuff "info" and thoughts to know I'll utilize the 5:7 winding version. Thanks to all that replied! 72, Jim Rodenkirch K9JWV
From: [email protected] To: [email protected] Subject: Two 2:1 transformers to choose from!! Date: Wed, 21 Aug 2013 13:23:37 -0600 I have two impedance transformers wound on BN 73-202 cores that I can use for the 2:1 impedance transformer I need for my FO0AAA delta receiving antenna. One has a 2 turn and 3 turn winding- giving a 4:9 impedance ratio. The other has a 7 turn and 5 turn winding, giving a 25:49 impedance ratio. I don't know which would be better - I believe the one with more turns probably has better coupling, but more loss?!?! I am splitting fine hairs here but....I am curious if one might say, 'Use "x" instead of "y," Jim....Thoughts??? 72, Jim Rodenkirch K9JWV _________________ Topband Reflector
