Parks on the Air (PODA)

COMMON ANTENNAS YOU NEED TO KNOW ABOUT, Everything acts like an antenna — sometimes, the antenna is you!

Antenna height changes the resulting antenna pattern, starting with mainly high angle radiation at 1/8 wave length then progressing through a lowering of the high angle as one approaches 1/2 wavelength. Then it grows more high angle radiation and then breaks into "lobes" at distinct take off angles.

Radio Frequency Interference (RFI)

As our lives become filled with technology, the likelihood of electronic interference increases. Every lamp dimmer, garage door opener or other new technical “toy” contributes to the electrical noise around us. Many of these devices also “listen” to that growing noise and may react unpredictably to their electronic neighbors, including Amateur Radio transmitters.

WIRES X – The Bible

My goal for creating this document ( which has grown into a book); is to provide a central point access for some, if not all, WIRES-X information, procedures and best practices on the uses of Fusion WIRES-X for all to use.

The 2019 Florida Statutes Flagpoles

Any homeowner may erect a freestanding flagpole no more than 20 feet high on any portion of the homeowner’s real property, regardless of any covenants, restrictions, bylaws, rules, or requirements of the association.

SARNET Video

The Most Effective Ham Radio Statewide Network. I have talked to Eric KJ4YZI on Sarnet, he has several very good video's.

Self-Supporting-Towers

The self-supporting G-Series towers are an easy, low-cost solution to get light weight antennas in the air quickly. By using the G-Series tower as a self-supporting structure, you minimize land area usage. They are functional in a wide variety of wind speeds.

How to choose a Rotor

Besides certain avoidable problems (such as upside-down mounting) and “Acts of God” (lightning strikes, etc.), the #1 cause of rotator failure is under-specification. The customer gets a rotator that is too small for his or her application, and its gears get ground to bits in the first wind storm which occurs.

What is a diode?

A diode is a semiconductor device that essentially acts as a one-way switch for current. It allows current to flow easily in one direction, but severely restricts current from flowing in the opposite direction.

All About Circuits

This free electrical engineering textbook provides a series of volumes covering electricity and electronics. The information provided is great for students, makers, and professionals who are looking to refresh or expand their knowledge in this field. These textbooks were originally written by Tony R. Kuphaldt and released under the Design Science License. It has since then been updated by members of the All About Circuits community and editorial team.
