I own 2 of these and they work wonderfully. And have owned Yaesu rotors for years - all models. My personal opinions: The controllers should be sold separately on ebay/swap forums. They should fetch
With 17ft of mast exposed, how much is in the tower? I have always been one to have close to half of the mast "in" the tower. I have a 21 ft .025 inch wall mast and 8 ft of it is in the tower - so 13
In my view, the discussion on OWA yagis is about the element count and the boom length. People will describe that they have a 5 el or 6 el yagi. However, an OWA yagi has 2 elements that are really cl
Rich. Cant comment on the STEPPIR. However the performance degradation of the yagi as you discuss at the band edges should be unaffected by the OWA feed. Its more a function of the element spacing de
Insurance is all about definitions and exclusions. If your town considers ham radio towers - auxiliary structures - like many do, then your insurance should cover it to the extent it covers auxiliary
I always align the tower face to allow a 2 leg boom connection towards EU for fixed yagis on the tower. To the south or West I build up a connection to the non-cooperating leg with some brackets, to
Dave, What wasn't described on this original thread is that you have 150ft of 55G available. So an antenna design is not in a vacuum. What are the goals of the antennas and what else is on the tower?
Don't confuse "verticals near salt water" with "verticals OVER salt water". N5OTs example is a vertical over salt water with a few wave lengths in all directions of exceptional salt water plane. The
I have 2 - 20M 4 el yagis at 35 and 80 ft. My terrain to EU is steep and favorable. Within 200 ft of the tower base it drops off 110 ft. I have extensively modelled with HFTA and done A LOT of on the
Have you used the TDR to see how far up the coax the problem is? If its showing "at the beam" - there is no way I know of to confirm what is the issue jus that its at the beam. Obviously, if the faul
There is a lot more important question on the table here than coax on an asphalt shingle roof (which in my opinion is a non-issue). If you can't access the space underneath the roof, how are you plan
Why is it that direct control of L and C are required? I use the MFJ high power tuner and have no issue with it on auto tune finding a good match for my 80M phased dipole array. Ed N1UR _____________
You take the cover off the dial indictor. Pull the indicator needle off. Push it back on pointing at the actual heading. You put the cover back on. Ed N1UR ___________________________________________
Since the climber appears to have survived, maybe a statement of what happened will be forthcoming. Until then, baseless speculation provides no value. Climbing is a dangerous activity. Just ask your
I believe the top output power in C6 is 250W. As someone who first did in band receiving on many bands up to 200W and then "graduated it" to 1.5kW, it a horse of a different color. I don't disagree w
Sorry - this was meant for tobband reflector. Ed N1UR I believe the top output power in C6 is 250W. As someone who first did in band receiving on many bands up to 200W and then "graduated it" to 1.5k
My preference would be to climb up the tower with the temporary guy. Attach it to the top. Drop the guy to the ground. Either climb back down or have a helper attach the guy and tighten it so that it
I have found the "point in the air" method works much better on monobanders than on multi band yagis and linear loaded antennas. Much better is to try and find an ability to get the antenna 20 - 25 f
My choice has always been high quality LMR240 (RG8X size). It would be about 0.4db for 100ft on 80M. There really isn't a better option. I use it on my 80M center fed slopers. Ed N1UR _______________
Rohn 55G is really not appropriate for a temporary set up. Its way too heavy to tilt up and you don't want to be assembling it with a gin pole if there is no concrete base. If something is so big it
