Antenna Tower Links →
Coax Junction Box at the Base of the Tower
The concept is fairly simple i needed to get nine runs of coax from the top of the tower to the basement and now it's also to the shop
Detuning the Tower, N4IS
Photo tower and system for receiving low bands
Detuning Towers, W8JIdetuning towersthe goal of detuning is not to avoid resonance, but rather to minimize re-radiation and/or current in the interfering structure

Assembling your antenna system
tie rods to connect the tower that supports the antennas, but usually little is known about the physical properties of these cables

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
