Hi Kelly: I think you will be okay using a coax balun...that is what I use on both my 80 and 40m Yagis now....I still have a relay at the driven elements of both beams since I want the baluns to be "
Assuming one has installed a crank-up tower with a motor drive...it confounds me why anyone would leave the tower up at all unless they are QRV. I use the US tower HDX-589 mdpl and NEVER leave the to

Hi Gary: For two years I ran the Force 12 EF-180B rotatable dipole at about 100' I switched out to my homebrew 2-el coil loaded Yagi in 2002 and it has been an outstanding DX performer. A direct answ
Just let the cable bundle hang from the top and let it "pile up" on the ground. Forget the stand-offs at each section. At VE6WZ I have the US tower HDX-589 crankup and at the top is a 3 foot stand-of

Julio...and others I do not wish to hi-jack this thread, but over the years I have seen this same comment repeated about a cable "retaining a set" if left in the same position. Why is this a problem
Steve: What is a "Fixed flaw" ???? I really do not mean to be difficult Steve, but exactly what is the science behind this?? Do you have a reference? Where did you get this information exactly? In my
Thanks for that info Grant: I think I understand your explanation. Cycling stress on the wire rope is understood. That is always a factor with rope rolling over a sheave I suppose. Differential stres
I just got off the phone speaking to US tower in California about this recent thread regarding stopping your tower and different heights to prevent a "cable set" failure. The representative I spoke t
Why is 2" separation a problem? There are numerous commercial Tri-band 6-2-70cm yagis that share the same boom....0" separation. It is all about tuning. Plug-and-play....."out-of-the box" commercial
Over the years on this list there has been a persistent thread suggesting it is essential to lubricate your crank-up tower cables. See the link below for a .pdf FAQ document from US tower wherein it
Ned: I have replaced the cables on my HDX 589mdpl three times. Slack on the pull down cable is a common issue after replacing the cables. The slack is only evident when the tower is fully up. (obviou

Rob Consider switching in some inductance at the feedpoint as needed instead of the tips. Easier to implement most times and the voltages are more "reasonable" at the feedpoint. At the tips the volta
Yes Jim.... For the last 5 years I have used my 80m Yagi elements for a phased rx array on 160m. It has been my main 160m rx antenna most of the time. I use vacuum relays at each element to switch in
