using SS It varies - I tend to use whatever is supplied. With plain nuts I would always use the Loctite. With Nyloc nuts I would only add the Loctite if the hardware was showing any sign of galling.
I use Blue Loctite 2400 which comes in a simple no-mess squeeze bottle. Apply 2-3 drops on the bolt thread at the location where the nut will be tightened, and while still liquid the Loctite will act
I tried split bolts, and they were greatly inferior to the crossover clamps. Split bolts do not allow crossover connections and the incomplete threads aren't strong enough to allow the nut to be cra
the mesh radials The wires at right-angles to the main direction will probably have little electrical effect; but if the currents in those wires are small then the losses (depending on I-squared) are
with Good points from Jim. 1. Mesh grounds have multiple current paths in parallel, so the individual wires don't need to have especially high conductivity. What does matter in a mesh screen is that
How There is no simple answer because SteppIR have gradually improved the design and quality of the fiberglass tubes and the EHU moldings. Today's SteppIRs might well survive in conditions where olde
aluminum make always If the threads in aluminium rotator castings aren't too badly damaged, a simple alternative is to use RED Loctite to fix short threaded studs permanently into the rotator base. (
HFTA does not require evenly spaced data points, so the 149-point limit in the data file is not the problem it might seem. If you are prepared to remove some redundant data from the computer-generate
Several good points there, about the variability of ferrite cores. Ferrites are, quite literally, "bakery products". Just like bread and cakes, the properties of ferrites depend on the correct ingred

As Roger says - it's easier to do than to explain. In this context, "relatively clean" is just fine. Although the adhering hot-melt adhesive doesn't look pretty, that isn't a problem. Think of it as
