Antennas : 160M- 160 Meter Ground Plane
- The 160 meter ground plane is constructed from #10 stranded insulated wire available in most hardware stores. The feedpoints / tiepoints use PVC pipe T-sections Article by W1TR

- 40m Vertical End-Fed Antenna
- A quarter wave vertical end-fed antenna for the 40 meters band. As all vertical antennas, also this aerial requires a good earthing system. In this project the ground is composed by twelve 4, wires buried in the lawn by using a spade to create a slit to drop the wire into.

- Wire Antenna Design Lengths
- The Classic Numbers for All Types of Wire Antennas at HF. Wire antennas need to be made a bit long and cut to resonance. They are affected by height above the ground and surrounding objects. In order to get an idea of the right place to start, certain formulas are generally accepted.

- Broadcast Antennas on Buildings
- When a broadcast antenna is to be placed on top of a building, there are special problems of feeding and grounding. The radiator is usually electrically short, that is, much less than one-quarter wavelength high.

- Notes on Designing LF-MF antennas
- A free book on designign LF MF antennas. The six chapters in the body of the book are limited to basic information which, combined with a little modeling or simple calculations, can be applied directly using graphs for special problems like inductor design.

- Double Half-Delta Loop RX Antenna
- This wire antenna was developed to offer for a small, low-band, ground independent directional receiving antenna, it requires only two support poles. It is basically composed by two interconnected half delta loops and is better than a single flag or EWE, and almost as good as two phased EWE in the same space.

- Optimizing Ground Radials in End-Fed Antennas
- An interesting article focused on defining the optimal lenght and number of ground radials in vertical, inverted-L, end-fed antennas. This article compares also the radial length vs number of ground radials to power loss in transmitted power.
