Ten feet is a bit low for tuning. A 40 meter dipole tuned at 15-20 feet will resonate about 10-15 KHz higher at 78 feet. Keith WD5DXL Which way should the resonant frequency go as the height above gr
What kind of rope should be used to haul antennas up the tower using a tramline? For a 150 foot tower how long should it be? Any recommendation on a supplier? TIA Keith WD5DXL _______________________
John, Thanks for the valuable info. I also received an off-list reply from David K1TTT. The tramline is Rohn 1/4 EHS and is anchored at a large pine tree about 190 feet from the tower base, directly
I have used the liquid electrical tape from Home Depot. It works quite well, and has stayed put on an outside coax connection for over two years. Lowes also carries it. It comes in a variety of color
I have two sitting at home, but am presently at the office. If no one has responded when I get home I will measure and send. BTW, the back has two holes, one for power cable and the other for control
My installation uses a 6061 aluminum plate bulkhead with female-female PolyPhasers mounted on the inside. I have not bothered to seal the connectors although it might be a good idea in the future. I
at 20'. At mid day, it outperformed stacks to 100'. Stacks of what? I am constructing 4 tribanders (C-3) on a 150 foot tower. They will be positioned at 152, 119, 86 and 53 feet. The top two and low
Friend of mine has two LPAs on separate towers and he loves them. He is also a contester. One covers 20 through 10 and has a 40 meter 2 element (shortened) beam about 10 feet above. Not sure about co
Not sure of the brand, but all of my grips came from Texas Towers and they are EHS also. They have a yellow painted band near the wrap-start point and a paper tag on the short end. I always start the
Nice station! Your SteppIR must have the complicated matching network to work for all bands since element positioning is a compromise with the design. This network is lossy. By contrast, a Force 12
blah....and a great antenna: SteppIR 4 element with 2 passive elements for 6m. Another nice station! buy it....right? Touché' Keith _______________________________________________ See: http:/
over the 3 element SteppIR. In return, you give up 1 - 2 dB on 20/15/10, 3 dB on 17/12 (as well as a proper match), operation on 6 meters ... as well as good F/R on 20-12. That's why I am building a
You obviously have never drilled out a rivet. You also do not seem to care about the need to climb your tower to do repairs on your antenna. And, finally, you must have little to no experience with c
Contesting is much more about experience, planning and operating skill than antennas. The SteppIR is still fairly new and that is why you don't see many serious stations using them, IMO. I think a Mo
I don't think the moving parts are a red herring at all. I am glad to hear about the reliability. Not sure what you are saying about the C-4XL regarding linear loading and helical hairpin. My only gr
This thread is getting quite long in the tooth. However, it caused me to wake up and realize I will be making a mistake to put up cat5 for the relay boxes on the 40 meter beams. Had not thought about
Sounds good. The C-3S is a light weight, durable antenna that has respectable gain on 20-15-10. Will they be phased, or just switched? I just ordered a C-3S from Tom N6BT at HamCom (Arlington, TX) la
Read further and you will find lots of comments from many on this list. Congrats on your purchase. A friend of mine recently obtained the same antenna and is quite pleased with its performance. Howev
Sure looks like the reflector is really resonating above 6940 once the antenna is in place. I would set the driven element to 7060 first with the reflector open, then lengthen the reflector until min
