I have read posts all over the intrawebs and have some questions:=C2- (Pl ease use small words and talk slowly): 1. It looks to me like the 'front/leading edge' 60 deg leg is bolted direct ly to the base leg which is grounded.=C2- How can the "active" (is that t he correct word?) be directly connected to ground? 2. I have read articles where the author is talking about "tuning" the ante nna after it is installed in a specific airframe.=C2-=C2-=C2- a. They talk about trimming/cutting pieces - what pieces and how much trimming?=C2 - b. They also talk about fooling with the dielectric section but I don't understand what physical dimensions/properties they are altering.=C2- Ar e they cutting aluminum or bakelite; or moving feed line screw holes; or ju st moving the bakelite piece around in small increments?? 3. SWR meter vs Antenna Analyzer=C2- a. I think that SWR applies to trans mitting, so is it relevant with respect to VOR antenna?=C2- b. What is an Antenna Analyzer and how does it work?=C2- (in 5 words or less) TIA for VOR Antenna 101 -Jeff ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message aeroelectric-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/AeroElectric-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/aeroelectric-list Browse Digests http://www.matronics.com/digest/aeroelectric-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
