When assembling Al -to-Al junctions in an Antenna, what anti-corrosion compound should be used at the joints? Kim N5OP "People that make music together cannot be enemies, at least as long as the musi
I asked the question to make sure something was needed for Al-to-Al and it seems it is truly is. Long ago, I was told that Al-to-Al was best dry because galvanic corrosion couldnt When I was In CO, I
From this thread, I learned that stainless steel and aluminum are a corrosive combination. I hadnt heard this before. Ive known that copper and aluminum are a corrosive combination and so the Jet Lub
I have experience with OxGard and it seems to work fine over spans of about 10 y in CO and OK. The stuff has petroleum-based grease with graphite and zinc particles. From what Ive read in this thread
In a similar vein, I'm helpingto rect an antenna in a relatively inaccessible location and want to minimize element vibration. I have no intention of tryingto fill each element with foam, but I've re
What do you expect EZNEC to tell you that you dont already know, at least in this case? What could it tell you that would change what you can do given your limitations? Kim N5OP "People that make mus
Ill display my benighted state by asking a question: why not place an auto-tuner at the feed point of the doublet? That way, the feed line is flat and the doublet can be any length, assuming impedanc
Yes, this includes mechanical issues if there's no center support. Then there's the entire issue of insuring there's no wire tension supported by the tuner itself. But except for that... Kim N5OP Wes
Terminals 1 and 2 are the big wires that carry motor current; the rest simply need to match terminal numbers at each end. Kim N5OP "People that make music together cannot be enemies, at least as long
I shunt feed my short (~55 ft) tower with a KLM KT-34A, a CushCraft 40-CD2 a DW3, a 2 m corner reflector and a discone and have never seen any adverse effects even at full legal limit. Kim N5OP "Peop
I'm investigating rotor that will fit the same bolt pattern as a T2X but that are a bit beefier. Mine works well, but in windy conditions, I can't turn may antennas due to wind imbalance. What beefi
At least my T2X manual says 2 1/16. It must be right because I use 1/32 shims with my 2 mast and all is perfect. Now for an embarrassing admission: I was ignorant of this for nearly 20 years and coul

I've had a T2X in an HDBX 48 for 30 y. It turns a 2" diameter, 1/16" wall chrome-moly mast. There are 8' of mast above the thrust bearing holding (from top to bottom) a 40-CD2, a WD3, and KL-KT34A (a
I forgot to add: you are right in that a 3/32" shim is needed for a 1 7/8" mast. Kim N5OP On 12/30/2018 9:41 AM, john@kk9a.com wrote: I never understood the popularity of 2" masts. Going smaller that

I'll add that as a research meteorologist, weather instruments are sort of a "thing" for me. Davis makes nice instrument sets, but sells each instrument separately, which makes it all more expensive
Yes! I forgot about Peet Bros. Their instruments are well made. I had one of their stations and liked it very much. The best part was, because it is wired, it had a heated rain gauge! It may sound si
