I forgot, but I think element trussing was discussed in ON4UN's Low Band DXing book and in Lawson's book. I am not at place where I can check. 73, Larry W6NWS I am toying with the idea of rebuilding
I had a Force12 80M rotatable dipole which is a bit bigger (65 feet as I recall). It used loading wires that also served as a support truss. The mast ends of the truss were attached to the ends of a
I have always put the pea gravel in the bottom as spec'd by Rohn. The way the legs are constructed and assembled on G sections I suspect there is very little water that gets in the legs. Probably mor
In the early days C3, EF 180B, and 240 generally used 0.125 inch rivets on the elements. The 180B had some 0.25 inch rivets as well if I recall. Booms used 0.25 inch rivets. The C3, for example, gene
I had failure on the 240XL element to boom plate where the rivets elongated the holes and the element eventually fell off. Bringing down a 2 el 40M yagi with only one element is not a lot of fun. I w
FWIW, I have used the same Ameritron RCS-8 since the 1980's without a problem. It does have open frame relays. I haven't priced one lately but they used to be relatively cheap in price. Mine is curre
For coax length one quick way to check is to insert say a 6 foot jumper in the line and if the SWR changes then coax length is probably the issue. If the SWR is unchanged with the jumper the issue is
There are a number of potential problems: 1. The balance point is just a few inches forward of an element that would be in a tower. Moving the mounting point forward might make it work but then you w
The original website was run by W0UCE who is now an SK and the site is no longer there. The 160M dimension was 33 feet on each side of the feed point and the 80M dimension was 16.5 feet. 73, Larry W6
Regarding the sticking brake: The Green Heron control box will attempt to turn very briefly the T2X the opposite direction from the desired rotation to assist getting the brake free. It was done beca
Bob suggested I post the following for those that might not have thought about using a ladder against a tree. I use a relatively cheap cargo strap with a ratchet to secure the top of the ladder to a
I believe the selling outfit in the US was in Oklahoma (c1979). I still have a TET tribander (bought in 1979 or 1980) but it hasn't been up in years. I may still have doc for it but it will take some
What about something like Slipp-Nott (not the sports mat!)? I think it is being sold by Tennadyne. Not sure but it may only fit a 2 in mast which wouldn't help you of course. 73, Larry W6NWS On 7/28
Try looking back about 2 months as there was some discussion about climbing harnesses on this group with several specific ones mentioned. 73, Larry W6NWS Need to acquire a climbing harness for new to
I used I beam material rather than pipe. I have a 25G (75ft)and 45G (100ft) both done that way. The I beams are anchored in concrete of course. I had tabs added to the I beam for the guy ends on the
I am interested in what you might get in response to your downside issue. I have a 4030 M2 antenna with an Orion2800 that tends to slip when I get high winds. I had a Slipp-Nott (sp?) that I put up w
Several years ago M2 would supply it. I needed some pieces for a KT36XA that were bent in a tornado and they did it. Perhaps they have changed but I doubt it. 73, Larry W6NWS 1 each: 1 1/4" x .058 x
