Stick the RG-58 cable into the middle of the feeder cable. Marked laterally for a better understanding
Long yagi 4 elements for 11mt
The antenna is a four elements Long Yagi, installed since last year at 12 meters above the ground
Loop antenna
Half Loop is certainly a familiar antenna to many people. Generally it is a square or a squared screen and most often it comes in the form of a QUAD antenna radiator
Magnetique 27-28 MHz
The critical piece on this type of antenna is always the variable tuning capacitor which is located at the hotspot of the antenna
Normal Mode Helix Antennas for HF Mobile, N2MH
The following table summarizes the data for the various coils I built. All resonant frequencies were measured with an MFJ-259

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
Build a Three-Way Antenna Switch and Displa To use a wireless relay to select one of two high current capacity power relays
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 factor
