      Greetings TOM!               RW> TW>> What i am desctibing is build directly using the LPDA antenna        RW> TW>> Theory Drawing on hte Internet.               RW>> Link?               TW> I sent a Liknk before and you apparently Ignored it.              I don't remember link from link...               RW> TW>> And is an Absolute copy Theory Wise as what you are talking        RW> TW>> about except for the using of a single boom with all the        RW> TW>> elements insulated from the boom and uses wiring in place of the        RW> TW>> Two Booms which perfom the same purpose as the wireing in the        RW> TW>> antenna I am talking about               RW>> That isn't LPDA theory...LPD antennas include the boom as an active        RW>> part of the antenna. What you've done is isolate the boom(s) from        RW>> being an active part of the antenna and only using the dipoles. I        RW>> really can't see building such a monster, when it is so much easier        RW>> to build a LPDA...               TW> Only the one you are talking about has two booms with the Boons being        TW> a part of the feel line to the elements.               TW> I have one of the antennas I am talking about on my roof constructed        TW> from the Pure Origional LDPA theory drawing,              You mean the schematic of such an antenna. Pure LPDA is built with two       booms and follows a formula, which is where the LP comes from.               TW> Which I perviously linked,              Link?               TW> where all the elements are insulated from the support boom        TW> and are connected by a crossover wiring system, as in the theory        TW> drawing, so All elements are connected to the coax. Half to the        TW> center conductor and half to the Shield.              With each element isolated from the others as the schematic shows?              I don't think so.               Have a day!               R\%/itt - K5RXT              --- GoldED+/W32 1.1.5-31012       --- D'Bridge 3.99        * Origin: HAM Radio, aka Amateur Radio. 804?
