I have a TH3MKII with a 30/17/12 dipole mounted five feet above the beam on a 54 foot Tri-Ex tower. I am thinking of replacing that with a 3 element StepIR. I am convinced it will be a step up in all

The biggest problem with bigger is the proximity of my tower layed over near the house. I originally laid it out to accommodate a cubical quad. When that went away in a hurricane I replaced it with a

Mike, the bottom line is the reflector of the TH3MKIV hits the edge of the roof as I lower/tilt the tower. The SteppIR will be about four feet longer on a side, so much worse. The trombone would be e

Perry, thank you for your help. I am going to get the RC1-Y-Digital-Rotor-Control, unless someone here has had a bad experience with them. It appears my controller is bad. If someone has the voltage

Okay Perry. I ordered one. It should be here in the next few days. I am getting ready to run phone patch traffic for the SATERN net and 14.300 and need to be able to turn the tower. Normally from her

Good evening. I have had a chance to consider the MDS controller, and I must say my initial impression is good. The MDS RC-1 is physically a third the size of the Yaesu controller. The first thing I

Jim, thanks for the comment. Yes, the new rotor motors ship with the seven pin male connector on the motor. The older motor has a larger six pin plug. I am looking for a source of both. If none are k

Good morning Hans, Are you talking about changing plugs on the rotor motor? Do you have a link to the kind of plug you are now using? I am going to redo the cabling to the tower, replace with all new

Thanks Alan, I am hearing the same thing from many and will certainly use it. I feel I have been very lucky over the years with this tower. Terry - W6LMJ _____________________________________________
