Analysis of a base antenna 5 / 8% u03BB fed conventional

MASTER GAIN-Gain-Master Antenna SIRIO fiberglass Mhz.736 25.5 to 30 cms.
Gain-Master is a 0.625% fiberglass u03BB tech
Works on CB and 10m amateur band

Completely designed by the electromagnetic simulation for maximum gain and optimize the radiation pattern and bandwidth.

Designed with the most advanced technology available is entirely made in Italy with high quality materials.

The new design of the radiating element (patent pending functions as a center fed dipole for all RF currents on the radiator are in phase and ground plane radials are not needed.

Coaxial coil at the bottom works like RF-decoupling network for optimal mast and feedline.

Made of fiberglass telescopic tube is grounded for the best protection against static discharge.

Gain-Master is the new standard in its class of antennas.

Gain-Master SIRIO GAINMASTER fiberglass antenna from 25.5 to 30 cms Mhz.736.

Analysis of a base antenna 5 / 8% u03BB fed conventional


The review found that the radiator 5 / 8% u03BB, although it is considered one of the best solutions for amateur and CB band, has some negative factors, one of the most important is the distribution of RF current to along the radiating element.

1 shows the current distribution, with its animated simulation of a classic antenna 5 / 8% base u03BB fed, it is clear that about one fifth of the total length of the radiator radiates out of phase.
This implies an elevation angle of maximum radiation appears to be between 21 ° and 24 ° with a considerable loss of signal on the horizon, on average, 0,9-1.4 dB. (See the 3D radiation pattern and its section.

Mast mount 35 to 45 mm. not included.
