- Page 5 2) ASSEMBLY 2.1) Take the aluminum plate E and the two tubes D. (Photo 01) 2.2) Position each of the tubes D on one side of the plate E, so that the red marks match the clamps. Note that the tubes should form a cross and two clamps will be free for later use.
- Page 6 Note that the nylon tab should be positioned toward the outside of the assembly. 2.5) In the same way as with tubes B, mount a tube C on each end so that the plastic cap is positioned on the outside. That way you will have an X-shaped set that will be the structure of your antenna.

- Page 8 3) ADJUSTMENT Your RH-DX1020 antenna is already set and centered for the lowest SWR at the following approximate frequencies: 20m - 14,150kHz 17m - 18,100kHz 15m - 21,200kHz 12m - 24,950kHz 10m - 28,400kHz In all bands, at the center frequency a very low SWR is obtained, with an increase of SWR for the ends of each band.

21,050kHz (CW subband), remove the tape and INCREASE the length of the antenna. This adjustment is critical, so you will have to increase only about 5mm (1/4”) on each side, reassemble the antenna and give the SWR. If you want the SWR to be lower at a higher frequency, SHORTEN the antenna’s length. -
