Building a High-Gain Cubical Quad Antenna for the 2-Meter Band: Tips, Formulas, Pros, and Cons
Introduction Cubical quad antennas have been a popular choice among amateur radio operators for many years, due to their relatively simple construction and high gain. This type of antenna is especially popular for use on the 2-meter band, as it can provide excellent performance with only a moderate-sized structure. In this blog post, we will discuss the construction of a 2-meter cubical quad antenna, including construction tips, formulas, and the potential pros and cons of using this type of antenna. What is a Cubical Quad Antenna? A cubical quad antenna is a type of directional antenna that consists of a square or rectangular loop of wire, supported by a framework of poles or wires. The loop is fed by a single coaxial cable at one corner, and the other three corners are connected to a set of elements called "directors" or "reflectors," depending on their location and function. The directors and reflectors are typically shorter or longer than the main loop, and thei
