A Homebrew Yagi for 1296 MHz DX
As none of the versions satisfied me I could not find a fast solution and started my own design by building countless prototypes and making gain measurements in free space
An interdigital filter for the 23cm band
Build a band-filter for the 23cm band, the following drawing of an nterdigital filter
Analysis of the G3LTF Dual Band Feed for 23cm and 13cm
The feed is a combination of two proven designs, an EIA dual-dipole feed for 23 cm

Take off angle of horizontal antenna For horizontal polarization, the electric field will move sideways on a horizontal plane, while for vertical polarization it will oscillate up and down on a vertical plane
Rx antennas 4Square Rx Vertical Array My frequency design of 1.825 MHz a 90 degrees line would be 33,70 metersinstead of the previously calculated 33,27 m
Calculo da Antena Bazooka A double bazooka antenna is a combination that has a complete coaxial wave multiplied by its velocity factor and a total end-to-end length of 1/4 wave for each side affected by another driver shortening facto
