OK, looking back at this, I mistakenly thought you were referring to the linear loading wires. My mistake. Is this the boom truss lines, or the 40M element LL wires that also act to truss the element

Interesting. I have a stack of MAG 620/340's on a 120' R45 tower and I have had absolutely NO trouble with my 40M elements. The lower one is a rebuilt antenna after an ice storm - the lighter (older)

I quit using the old B-1 balun. I use the "Ugly balun" on all antennas. Works extremely well with no heat degradation. 73, Jamie WB4YDL Sent from my iPad _____________________________________________

Is it a coil or coax ? Yes and yes ! :) I use lightweight 3 1/2" sewer PVC and use it as a form for wrapping the appropriate number (depending on frequency) turns of coax (I had Buryflex on hand). Yo

The best bang for buck on 5-band yagis when I was building my station was, in fact, the Force 12 XR-5. I have a short stack on a 72 foot crank-up tower and they just work - very well. I understand th

I have to agree with Jim here. The old B-1 balun Force 12 sold was not very good - I managed to burn out a couple. The SWR was never as flat as with the 'ugly balun'. :) 73, Jamie WB4YDL AAARGH! Most

Yes, I use quite a bit of LMR-600, a very nice 1/2" cable. You will need the H4 piston crimper - I borrowed one from the local cable/tower guy. I run LMR-600 from the SPG to the tower, then Bury-Flex

That's what I do - Kellum grips on all cables, tape together, and they all share the load. 73, Jamie WB4YDL why go to all this trouble when you can use a Kellems grip to hold the coax? Rick N6RK ____

I haven't seen much about the tilt plate as relates to a SB mount - more for a yagi. I'm not sure I could answer your question on this one. 73, Jamie WB4YDL Sent from my iPad ________________________

I like the Hexbeam, but I also like that 3rd element in the SB (and for 10M, 3rd and 4th elements). To me, it's just a superior design. I think I could walk up the SB on a mast after being built on t
