   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!
