Maybe it's a type, but VEC's are volunteen exam coordinators. I wouldn't expect that pool to be a source of expertise in this area. Al AB2ZY I am looking for a PE, who is licensed in South Carolina,
Based on a quick look, the original poster looks like he's got about 18 sq. ft. of wind load on a rotator advertised for "medium-large arrays up to 20 sq. ft.". I'm sure some derating is in order giv
Of the 3 digit alloys, the 200 and 300 series (most common) are non-magnetic. The 400 series is magnetic, but less corrosion resistant. Al AB2ZY Maybe so, maybe not. Most SS is non magnetic, but ther

Not if the material has been properly annealed. Austenitic alloys, which the 300 series are, are non-magnetic by definition. Cold working and some finishing operations can alter the crystalline struc
The problem with the 300 series stainless steels is that they cannot be heat treated. Using the McMaster-Carr website, compare 316 7x19 with galvanized steel. For a given diameter, it's about half th
That is really tempting, but you have to be careful. Since you can't tell how much soil is being washed out relative to the pipe diameter, you could end up with a sinkhole. Not some car swallowing mo
There's always a ground mounted vertical, such as the Butternut HF6V or HF9V. Considering that they are omnidirectional and long (in wavelengths), they are quite effective on 40-30-20m and will handl
If you know the diameter of the element you can make a first order approximation. Multiply the diameter (in inches) by the length (in inches) for square inches, then divide by 144 for square feet. Th
There are two ways to do this that I know of: Hire a light specialty trucking company. Often they also do local household moves. Probably the most expensive option. Call one of the many LTL* carriers
Brokers for independent truckers deal in full loads. Hiring a semi, empty except for a tower, to drive from CA to OH will cost nearly as much as the tower. Full loads are charged by the mile. The LTL

1/4 wave stubs can be made using just an SWR meter and a transceiver. Set the transmitter to the desired frequency. Connect a dummy load to the antenna jack through a tee connector. Connect the stub
