You pretty much have to avoid the house. As you surmise, even the North side is going to be a heat source or sink. I did not start getting decent readings - ones that compared to Wunderground, etc -
Gedas, Imagine a stack of upside-down, white plastic bowls (about 7" dia, quite thin due to their dollar store origins), spaced from each other by a repeating triangle configuration of 1-1/2 inch or
I'm with you, Chuck. The torque is additive regardless of which side of the mast the antenna(s) are on. 73, geo - n4ua _______________________________________________ ________________________________
I have a brand-new (well, New Old Stock) switch you can have for $10 shipped. It has the return spring installed. 73, geo - n4ua _______________________________________________ ______________________
Prop pitch motors came with brakes, sort of a disc brake; the first step in converting them to ham use is to remove the brake assembly from the bottom of the motor. It took a slug of current to opera
Well, John, I have measured the functional equivalent. I once ran a piece of coax on the ground to a 160 rx array element. It was in the Fall and I didn't notice that it ran by the front door of a gr

You will almost certainly have to orient the 40 m dipole at 90 degrees to the beam (parallel with the tri-bander boom) to avoid interaction with 15 meters. 5' separation is usually enough. 73, geo -
Tom, I have two PP in service, both on Rohn 45. For both, I fabricated a custom rotator plate from 1/2" aluminum plate and pressed in a new seal that fits the OD of the PP output shaft. I used a Chic
Paul, Yes, my added seal is part of the rotator plate and would stay in place when you pull the PP from the plate. At Tom's request, I'm trying to find a drawing or pix of what I did back then. 73, g
This is one of the two PP plates I made. One PP rotates a conventional mast on a tall R45, the other rotates a 105' rotating tower. In both cases, all axial force is resisted by a tower bearing; this
