Patrick, Solid, well thought out info. I love your disclaimer clause ! I am installing an Orion 2800 in my tower soon and this thread is very timely for me. Great information from you guys...........
The alligator clips would not be satisfactory. You are setting it up for 1500W. The high voltage points on a dipole are at the ends and alligator clips and will very likely cause arcing. What I did o
Steve, I like your method for raising an installed mast. I will be lifting my mast up when I take out my Hy Gain Tail Twister and replace with an Orion 2800 in a couple of weeks. I assume you used a
I'm with Jerry on recommending the M2 OR2800. The Green Hornet RT-21 you have will work beautifully with it, (better than the M2 controller) Look at it on the DX Engineering web site. ( I am not affi
Grant, Great solution to broadband our 80M dipoles, thanks for sharing ! I am going to try it on my 80M inverted V. 73, Bob K6UJ On 4/25/16 2:49 PM, Grant Saviers wrote: I think the simplest broadban
good point Kevin, Ron was able to free up the motor shaft with the WD40 and get it running. An application of lube would be good now to follow up. WD40 is mostly a solvent and very little actual lubr
Ralph, I researched rotators for a while and decided on the OR2800. It is a very popular unit designed for large antenna loads and is used by a number of big contest stations. It has proven to be ver
Jim, I forgot about the mast clamp in my earlier post. I got the K7NV clamp for my OR2800 and as you say it is the real deal. Extremely well made. Bob K6UJ The M2 OR2800 will handle up to 35 square f
I agree with Wayne. The synthetic grease does not break down at higher temperatures and maintains the same viscosity. Avoid petroleum grease because it will break down and the viscosity does change w
Jon, Great pictures of the install ! thanks, Bob K6UJ Utilizing SKU #0162563 1/4" locking washers with an outside diameter of .450, I found that they fit perfectly above and below the spacer on my M2
Eric, Check out the QST version mentioned earlier. Looks pretty good to me and much cheaper than the D140. Bob K6UJ 73, Eric W3DQ 73 de KG2V On Apr 27, 2016, at 2:31 PM, Eric Rosenberg <ericrosenberg
Eric, I like Jim's suggestion. For DX this would be a better antenna to supplement your C3 on the roof for 40 meters because it will give a nice low angle of radiation. It will knock the socks off a

Gene, I agree with you 100%. Your very last sentence should have been the first :-) It isn't the torque of the rotor to blame. What needs to be done is provide isolation between the rotor and the mas
Hi Rag, Yes that is it. It is commonly listed as a drive shaft flex coupling or flex coupling. All cars have them. They are designed to mate with the respective automobile drives shafts so our challe
Jim, Thanks for the good background info on the flex discs for our ant masts. I used to have Leesons book. Wish I still had it to check out his BMW flex disc configuration. I had to chuckle about M2
Peter, I see the flex disc mounted above the rotor in the second picture. Is that a thrust bearing above the flex disc ? Bob K6U http://m2.i.pbase.com/u13/df3kv/large/21834952.Kerpen1.jpg http://m4.i
Grant, From what I read their main function is to dampen the torsional shock loads. Here is what Mercedes Benz says: "The flexible discs serve two functions on the vehicle. Primarily to absorb excess
I remember the rope dampers Grant. I had the same issue and resolved it with the poly rope. I went out to my back yard and found element sections stuck in the ground like they were shot like an arrow
Jon, I really like this "steel and rubber sandwich" :-) design right on the Orion mast plate. Your reasoning makes sense to me. Plus, looking at the picture, it just looks right, hihi. It would be si
