ZL speciale 10mt
The antenna the ZL Special seemed to indicate gains as high as 7 dBd and front-to-back ratios as high as 40 dB.2 moreover, the antenna was relatively simple to construct

5 elements "vee"log-yagi for 10m
5 elements "vee" log-yagi for 10m band- boom lenght 4mt, Gain over 10 dBd
2 element-HB9CV-Beam
The HB9CV-Beam is a 2-Element-Yagi with two driven elements and was introduced by Rudolf Baumgartner
A 5 element Yagi for 28MHz
This is a high-gain, wideband OWA Optimised Wideband Array Yagi which covers the whole of the 10m band with an SWR of less than1.1:1 from 28-29MHz
Antena Direcional de 5 Elementos para 28.5 Mhz
Gamma match will be made with a 1/2 "aluminum tube and a 75 cm coaxial piece of RG8 without sock and sheath inside the tube

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
