Antenna dB – The basics
Antenna dB (decibels) are a unit of measure used to describe the gain, or amplification, of an antenna compared to a reference antenna. Decibels are a logarithmic scale that expresses the ratio of two power levels, and they are commonly … Continue reading

Isotropic antenna
An isotropic antenna is a theoretical antenna that radiates equally in all directions, with a radiation pattern that is completely symmetric around its axis. It is often used as a reference antenna in radio frequency (RF) engineering to compare the … Continue reading
RCAF’s Antenna fundamentals
In 1959, the RCAF – Royal Canadian Air Force – made a serie of interesting training video clips on Antenna Fundamentals, with the help from the Canadian National Film Board. I love these old training documents, they hold a gold mine of … Continue reading
Understanding Antenna Gain in a Few Minutes
I often enjoy reading on a topic and then try to summarize it in a short article on this website. But today isn’t the case. Sometimes a simple instruction video does a much better job than all the words I … Continue reading
SWR analysis of a Alpha Delta DX LB Plus antenna
This article will show you SWR analysis of an Alpha-Delta DX LB Plus antenna installed 40 feet off the ground in an inverted-V configuration. The antenna ends are approximately 15 feet from the ground. I explained in details the tools … Continue reading

SWR analysis of a G5RV antenna
For the past few months, I’ve been tinkering with the idea of improving my current antenna situation, which includes a full length 102′ G5RV (10m-80m) installed horizontally at approximately 42 feet. In order to proper install and tune new antennas, … Continue reading
