broadside

160 meter broadside/endfire array - AA1K 160 meter BS/EF TX array

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

Stacking broadside collinear - One popular rumor or thought is that antenna gain doubles every time we double the number of elements

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
