(Apologies, Ed, I was tied up yesterday with Radio Club Secretary work.) The answer to your question is "With great difficulty!" All the things that can be done relatively easily with coax feedlines
Granted that 50-60 countries are an easy chip shot from anywhere in Europe, but the remaining countries require reaching out much further. 73 from Ian GM3SEK few ____________________________________
It was only an idea, but at least I can share the thinking behind it... The aim is to use a HF (20-10m) beam with insulated elements for top loading the whole tower on one or more of the LF bands, so
Sure, but maybe not right now... I'm cleaning up the drips of oil from under the engine. 73 from Ian GM3SEK _______________________________________________ __________________________________________
Does anyone have a EZNEC file for the F12 XR5 they could share with me? I am having trouble getting a response at 12 and 10 meters. Twenty, 17 and 15 look OK, albeit 17 and 15 are slightly low in fre

Below the feedline choke, the outside of the coax is (or should be) almost completely dead to RF, so it can then be taped to the metalwork without further problems. But taping the choke itself onto t
Thanks for the thoughtful comments, Jim. That last point is entirely fair: we *should* be able to connect an "antenna analyzer" to an antenna, without it falling over due to strong received signals.
One thing I forgot: falling ground on the far (shadowed) side of distant ridges can almost certainly be simplified in quite a brutal way. This might be a good first target in step 3. -- 73 from Ian G
That's correct. The missing image is of a pair of square plates in galvanized steel, that bolt together with interlocking fingers to make crossover connections. They're just perfect for the stock fen
Hi Guys Thank you for all the replies, some great ideas there. Also, particular thanks to Ian GM3SEK for the .pdf - just what I was looking for Ian, and cheap too :) 73, Jack ________________________

The grades of Loctite are roughly color-coded into: Low strength (purple aka pink): Easy disassembly using hand tools [Used by clock and instrument makers for tiny screws.] Medium strength (blue): Di
Someone else is sure to comment on the choke baluns... Betcha they did: hot melt glue. Ordinary translucent glue sticks (not the yellow or white kind) are basically polypropylene, which is an excell
Many thanks to all for the various ways you have implemented the coax runs you have designed. I think I will look into a combination of what you all have done and pretty much solve my problem. I real
I have searched the archives and found only the mention of the plug (maybe AMP/TYCO), but no actual part number. I am going to call Yaesu Monday, but does anyone have the P/N of the mating (plug) con
Now that I have a new crank up tower less than 3 months old, what do you all recommend I inspect regularly, besides the cable/pulley integrity, winch operation and overall structure? What should I lo
