      Greetings Ed!               RW>> This kind of antenna experimenting is what brought me to        RW>> Amateur Radio in 1970...now that I could work VHF and UHF, the        RW>> antennas I built were much easier to handle...               EV> Another antenna I had 'thought' about almost 50 years ago, but never        EV> made was the 6 Meter Corner Reflector mounted horizontally.        EV> I thought it looked real neat, but even if I used Hardware Cloth for        EV> the reflector element it would probably get Blown Down in a Storm as        EV> big as that thing would be if I made it for 50.7 Mc/s.              You don't have to use hardware cloth to accomplish that. My corner       reflector yagi for HDTV is made of tubing. At 6mtrs, it would be half the       size of one for 10/11mtrs.               EV> I saw a HF Discone Antenna was used on all four of the AirCraft        EV> Carriers I served on while I was in the U.S. Navy, and also being        EV> told it was a BROADBAND Antenna that was used to Transmit on a range        EV> of frequencies from (IIRC) 4-30 Mc/s (using an Antenna Coupler/Tuner)        EV> really made me drool over wanting one of those MONSTER Vertical        EV> polarized antennas.              Which reminds me of connecting the coaxial output of a CB radio to the       tower of an abandoned radio station tower.               EV> I 'Think' I recall that several Transmitters on different frequencies        EV> could be connected to the Discone (through Antenna Tuners) and used        EV> at the same time.              That's how a repeater works. It uses tuned cavities to allow the xmitter       to use the same antenna as the receiver w/out interferring with each       other.               EV> During Air Craft Landing Operations the Discone was tilted 90 degrees        EV> towards the outside of the Ship making it a Horizontal Antenna, as        EV> far as I know the Transmitters and Antenna Tuners didn't have to be        EV> readjusted               RW>> And you guys thought CB'ers were nothing but skip talking        RW>> truckers and hillbillies...               EV> I waited to reply to your last comment until I thought what to write        EV> about Class D Citizens Band to You, as this is a Amateur Radio Echo        EV> and not a Citizens Band Echo.              Ok.               EV> As I understand it CB'ers only use FCC Approved Radios Made For the        EV> Citizens Band Service For Channels 1 - 23 Only, until the FCC        EV> increased the number of Channels Licensed CB Operators could Transmit        EV> on to 40, with a Power Level Not Exceeding 5 Watts.              Correct.               EV> Anyone else transmitting on a frequency not authorized by the FCC,        EV> AND/OR Transmitting with a Power Level above 5 Watts is a BOOTLEGGER!              An unlicensed radio operator.               RW>> Anybody interested in building UHF stacked Quagi's, let me        RW>> know..               EV> That sounds like stacked Quads, is that what a Quagi is?              No. A Quagi is a yagi with quad-loop driven and reflector elements.                     PS - I'm the E-listed moderator of this echo and anything 'radio' is on       topic in any of my echoes.                      Have a day!               R\%/itt - K5RXT              --- GoldED+/W32 1.1.5-31012       --- D'Bridge 3.99        * Origin: HAM Radio, aka Amateur Radio. 804?
