EI7BA Multiband Cubical Quads projects, includes two elements quad antennas for 10 12 15 17 20 meters band. Performance considerations, detailed pictures and construction notes.

The Inverted L antenna is a versatile and efficient design suitable for small gardens, allowing amateur radio operators to operate on multiple bands. This project outlines the construction of a 5-band inverted L antenna, which can cover HF bands effectively. The design is particularly advantageous for those with limited space, as it requires minimal ground space while providing good performance. The antenna can be easily constructed using common materials, making it accessible for both beginners and experienced hams. In this guide, GM0ONX shares detailed instructions on how to build the inverted L antenna, including dimensions and tuning tips. The project emphasizes the importance of proper installation and grounding to ensure optimal performance. Additionally, it discusses the antenna's compatibility with various transceivers and the potential for portable operation. This resource is ideal for hams looking to enhance their station with a multiband antenna that performs well in limited space.

HA2NON W3DZZ antenna project with pictures and construction details

This article was reprinted to assist new hams at building their own 2 metre antenna. This design is very rugged and can be built for a few dollars with most of the parts available at your local Home Depot.

Based on a W4TWW project and modified by KN4LF

This project describes an ARDUINO based automatic antenna tuner, for an end-fed half wave (EFHW) antenna, working on 20 & 40 meter bands

This project is about a cheap way of building a colinear antenna for VHF 145MHz, and having about 10dB more gain than that little 1/4-wave magmount

This Field Day Vertical Antenna project is the result of many years of attending various field day sites and realizing that what was needed is a simple, easy to assemble vertical antenna.

These devices are called Traps, but they are actually more like frequency sensitive switches. They are parallel resonant, high Q, tuned circuits which provide a very high impedance at their frequency of resonance.

Adding an external antenna to the Belkin F5D7050

This antenna project came out very nice. It's a rugged homebrew multi-band trap vertical antenna that works the 10, 15, and 20 meter amateur radio bands. The antenna can be mounted on the ground or on a mast. Mounted on the ground the antenna has a low take off angle for working DX. If mounted on a mast the antenna will acheive both a low angle as well as another radiation lobe that has a much higher take off angle.

Moxon antenna project, each side is 51 feet long and the turned in sections are each 7.7ft long. This antenna performed similar to a full size two element yagi for 40 meters.

The best way to describe a go-box is a complete amateur radio station in a box. An example is described in this article. The project describes building a portable amateur (ham) radio station, known as a "go-box," housed in a durable orange Pelican case. The go-box contains all necessary radio equipment except for external power and antennae, which are carried separately. It includes items like a Yaesu transceiver, power supply, antenna tuner, speaker, and a clock. The case is designed for mobility and visibility, with a vertical layout to allow in-vehicle operation. Future upgrades might include cooling fans, an LED lamp, and built-in antennae for better functionality in various conditions.
