I can confirm the Sinclair docs show the strongest signals broadside to the folded dipoles in their bi-directional antennas (1/4 wave spacing from the mast instead of 1/2 wave spacing). -- Nate Duehr [email protected]

The instruction sheet for the SRL235-2 says the opposite, that maximum radiation would be perpendicular to a line drawn as described. I can scan a page from the Sinclair instruction sheet to back up this statement. Paul N1BUG Jeff DePolo wrote: > If all of the elements are parallel as in your photo, then it's > bi-directional.
