UA6AGW Balcony Antenna for the 20 meter Band

(Version 20.23.63)

Aleksandr Grachev, UA6AGW

The antenna, working Version 20.23.63, has sizes 1 x 2 meters and designed for installing at a limited space. The antenna made like an experimental one and showed good result at the Air test. Figure 1 shows schematic of the antenna.

As it is shown from the Figure 1 the schematic of the antenna is traditional as for all UA6AGW antennas and does not required additional comments. Design of the antenna is shown on the Figure 2.

Design of the UA6AGW Balcony Antenna:

Main loop made of from a ½ inch coaxial cable used at sites of the cell communication. Two horizontal vibrators of the antenna made of aluminum Hula Hoop in diameter of 90- cm. The Hula Hoop is cutting at the place of the jointing. Then the ends of the rings are separated on the distance 3- 4 cm with help of a plastic insertion. The Hula Hoop is connected to the main loop with help of a tinned copper wire in diameter of 3- mm. The wire is soldered to the main loop and connected to the Hula Hoop with help of a clamp.

Tuning capacitor is placed inside a plastic electro-technical box. The capacitor should stand the power going to the antenna in common case (at 100- W transceiver) the capacitor should have gap between plates in 2- mm.
