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.
