There are below described experimenters
with UA6AGW Antenna made by Sergey Tetuyhin,
R3PIN. Sergey would like create an UA6AGW Antenna for 2- meter
Band. He did not have schematic of the antenna for 2- meter Band.
He made two antennas that he believed would work at the 2- meter
Band. However his attempt was not successful. But Sergey during
the experimenters found some unusual sides at UA6AGW Antenna.
Both antennas were made accordingly schematic shown at Figure 1.
Experiment # 1
of the Antenna
First antenna made by R3PIN is
shown at Figure
2.The antenna was made as a table design. Height of
the antenna was 45- cm. Loop of the antenna had diameter 13- cm.
It was a copper tube in 8- mm OD. To make a “copper tube coaxial
cable” inside of the tube was inserted plastic with central copper
wire that was got from a piece of an old 50- Ohm coaxial cable.
Plastic with central copper wire was in 2.5- mm diameter. Coupling
loop was made from the same copper tube. Coaxial cable was soldered
straight away to the coupling loop. Coupling loop had no electrical
connection to the loop of the UA6AGW Antenna. Figure 3 shows coupling loop at
Antenna whiskers had telescopic design. The whiskers
may be moved along the antenna loop by screw clamps. Capacitors
C1 and C2 were Air – dielectric with capacitance 8- 140- pF.
