Antenna gain, front-to-back, front-to-side and bandwidth are the 4 properties of an antenna that must be balanced to suite the designer’s needs. It is possible to maximize all these properties but then we would be coming up with a design that is a happy medium.
8 mar 2022 · overview. When a full-wave loop is used with square loop parasitic elements, it is often called a “cubical quad” antenna (or just “quad”). Such antennas can be built using other shapes, as described in the section on full wave loops. An array with triangular elements is often called “delta loop”.
This antenna design has been built for both the ten and two meter versions and I have used them for T-Hunting and in two CVARC Field Day events with good results. Figures 2 and 3 show the calculated antenna patterns and performance.
Build a Stronger 2 Element Quad. A Different way to construct a tried and true antenna out of PVC, especially for the 10 meter and higher frequencies. By KB3TTP. (Updated Feb, 2012 - see bottom of article) Editors note: Quad antennas are notorious for being difficult to keep in the air.
Don’t be disheartened if you happen to live in a community with difficult antenna restrictions. In addition to being inexpensive and simple to construct, this quad antenna is also compact enough to be placed in an attic! If you want an 11-dBi-gain beam antenna for less than $1 per dB, here it is!
4 sie 2023 · This is the common construction method for rotatable quad antennas below the 2m band (including HF). For multi-element antennas there are two common methods: either use a standard boom with spreaders for each element in a flat plane, or angle the spreaders out from a common hub attached to the mast.
