Switching box of the 4-square array connectors for HF

project I wanted to erect two 40-meter stand-alone verticals

upgrade the 160-meter antenna system

3-element array on 160 meters, the system is very good

It is an antenna system which

This article explains how to improve the front-to-back (F/B) ratio of the classic

system in use here on 80M is a 3 Element, in line, phased vertical array

This array the SWR from 3.5 to 3.9 is below 1.5:1

Stealth Generation 4 - 22-element 160m-6m Directional Array

A 124' rohn 25 tower as a driven element with a wb0w insulator section

I noticed that I really did not use it in the array application

Verticals antennas do require a lot of room for properly working

Four separate verticals are arranged in a square, a 4-square array, one vertical at each corner of a square

4-square was transformed into two reversible 3-element arrays

A combination of two rotating broadband magnetic

A phased array antenna is composed of lots of radiating elements

It's a 6-element vertical array which is designed for 40 and 80 meter operation

The wire verticals are 1/4-wavelength about 33' tall at 7.050 MHz
