- The Double Bazooka Antenna
- The Double Bazooka Dipole is a very efficient single band antenna which is very quite, and does not require the use of a balun. This antenna consists of coax (RG58) or other 50 ohm type with the shield split at the center and the feedline attached to the open ends

- K7MEM Center-Fed Half-Wave Dipole ( 3-30 MHz)
- A Center-Fed Half-Wave Dipole is probably the simplest of antennas to construct and use. It is usually suspended between two supports, from it's end insulators, and has the feedline hanging from the center.

- 20 thru 10 Meter Fan Dipole
- The 20 thru 10 meter dipole is constructed from #10 stranded insulated wire available in most hardware stores.
The feedpoint uses an 8 inch long section of 2 inch diameter PVC pipe. A section of wire joins the elements at either side of the feedpoint to avoid the inductance of square knots that I use on lower frequencies by W1TR

- Feeder Radiation
- Connecting centre fed antennas, dipoles, yagis, rhombics, loops to coaxial cable, unless care is taken, it is not difficult to end up with feeder radiation resulting in power loss and the radiation characteristics changes
