RX3MS Helical Antennas

 

 

33 meters of twin wire 300- Ohm TV Cable was wound around a bamboo fishing pole in 5 meter length. Line on the antenna up end was opened.  Line at the antenna down end was closed. A transformer was installed at the antenna. Transformer was made on to a ferrite ring in dimensions 60x40x10 (ODxIDxH). It were wound by a twisted wire 8 turns, schematics is shown in the Figure 1. Antenna had grounding. It was made by wire in dia 3- mm that was connected to aluminum tube in 3- meter length that was inserted to the ground. The antenna could be tuned from 1.8 to 30.0- MHz.

 

Figure 2 shows MAXI RX3MS Helical antenna. The antenna was made on the mast in 10- meter length. A dry Pine Tree Pole was used to make the mast. On top of the mast was installed a 7- meter long plastic fishing pole. 30 meters of twin wire line in plastic insulation was wound around the plastic fishing pole. Line on the antenna end was opened. The same line was downed to the balcony rail.  A transformer was installed at the antenna. Transformer was made on to a ferrite ring in dimensions 60x40x10 (ODxIDxH). It were wound by a twisted wire 8 turns, schematics is shown in the Figure 2. Antenna had grounding. It was made by wire in dia 3- mm that was connected to aluminum tube in 3- meter length that was inserted to the ground. The antenna could be tuned from 1.8 to 30.0- MHz.
