Mar 3, 2021 · If you need a number to start, twenty 32-foot radials will give you a workable system with most vertical antennas. You might consider 65-foot radials if you use the low HF bands.

In this section we will take a look at ground mounted and above ground mounted vertical antennas, especially with respect to the radials and try to make some sense out of the subject.

Shorter vertical antennas, such as Hustler's BTV series, Hy-Gain's AV-14AVQ, AV-18AVQ, and similar antennas with trap or coil loading under 30 ft. in height are good candidates for above …

ground stud is no more than 8” - 10” from the radial field. Any straight vertical wire going from the EHU to the radial field adds to the antenna length and causes a mism

If the radials are buried or lying on the surface, at least 16 radials, each at least a 1/4 wavelength at the lowest operating frequency, and don't worry about resonance: just get as much wire in …

This calculator is designed to give the vertical length (height) of a quarter wave ground plane antenna, and the length of each of the four radials

How many radials do I need for a vertical antenna? This document covers the topic of ground mounted radials and how to maximise the antenna’s performance through the radial bed that …

In his article, N4UU gives a formula that enables one to calculate the optimum number of radials for a vertical-antenna ground system, when the frequency, soil conductivity, and total length of …

I have been chasing DX on the low bands for more than 15 years and using vertical antennas for most of that time. I graduated from 1 vertical to 2 verticals to 4 verticals and always with the …

Use our simple calculator to determine approximate dimensions of materials needed to build a vertical antenna.
