Four over Four for 144MHz
- This article describes the 144MHz horizontally polarised antenna at VK1OD in November 2008.
The antenna uses two identical four element arrays that were constructed around 1970
W1ZY 40 meter moxon antenna
- W1ZY's 40 Meter MOXON is the product of 9 months of experimentation. The final array is reversible and constructed from No. 12 insulated wire fed through two RF current baluns
The Curtain Quad
- The Curtain Quad is a broadside array of 7 to more than 200 elements using a very powerful but seldom used method of power distribution

The Gain of an Endfire Array
- This article looks at the maximum theoretically possible directive gain that could be obtained with an endfire array of given length or number of elements, and compares this with practical results in the literature.
BiQuad Antenna for 144/440
- This is a vertically polarized Broadside and Collinear Array each Loop is a vertically polarized Broadside Array both the right and the left side of the Loop is a bent 1/2 wave dipole working 180 degrees out of phase with the other one and that gives you 4.15dbi of gain by KE4UYP
