Indoor Vertical Antenna
The vertical element consists of 2 one meter pieces of aluminum tubing used for hanging curtains. One piece is 1/2 in diameter and the other is 5/8 in diameter, so they could be telescoped
Isotron antenna for tight spaces
Realization of the antenna. You need a gray PVC tube 32 mm in diameter and 1 meter long. The choke will be made with sheathed electrical wire 2.5 mm
Linear loaded short dipole
My linear loaded dipole on both sides by 1.8 m in order to cover the 20 m band. SWR is ok without modification of the 1 : 4 transformation line
Multiband-Dipol DO-Antenne
A multiband dipole was created for the 80m, 15m and 10m bands with a length extension of only around 19 meters
X-Beam antennas
The X-Beam is a high-performance broad-band antenna that is ideal for Ham radio operators with limited space

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
