Today I finished burying the last radial on my 160M Inverted-L 4-square - yippee! After an hour of relaxation, decided to study radial benefits for my 80M K8UR style 4-Square for 80M - I know - I've
A while back I posted a query looking for folks who had tried 4-Squares over sloping terrain. Modeling showed that degradation would be slight but it is always good to find real world evidence.... I
I'm in the process of putting up a K1ZM style 4-Square for 160M meters. (K1ZM is 4 inverted-Ls). I measured the terrain elevation and was surprised to learn that the slope was greater than I had envi
I have no comments about Ron Block but wanted to add that the support that I have received from PolyPhaser has been quite good including customer followup to ensure that I was taken care of... My ord
With all the discussions on 4-Squares, thought I'd mention another approach featured in ON4UN's book and previously written up by K3LR in QST. The alternative I use is an array of 4 80M dipoles suspe
No question that a high 80M beam would win but I can sure turn my wire array faster - hi... I figure that the wire array improved my 80M dipole performance by about 10dB which puts a Texan working Eu
My towers are going up on a wooded lot - the canopy is clear under the guys but there are trees to each side. Does anyone have a rule of thumb on high high Phillystran needs to be above trees to insu
My question relates to how widely I can space guy wires on a Rohn 45 tower. I would like to go beyond the approximately 0.8 ratio suggested by Rohn to accommodate the turning radius of a beam that wi
Thanks for the replies to my question about guying spacing... My question related to any hazards to spacing guys wider than manufacturing specs. All comments were that the manufacturing specs were fo
I have used the IIX gate successfully for a small beam sidemount but have some concerns about it rotating around the tower with larger long boom antennas. I've heard from several folks that this has
