Well, it depends mainly on your terrain, but, generally, the higher antenna will exhibit better low-angle performance (DX), and the lower antenna will exhibit better high angle performance. You shoul
Keith, "appliance operator"... So, what, real HAMS use linearly loaded Yagis? Real HAMS use LPDAs? That's the funniest thing I read all day. I can't imagine what attribute of a SteppIR antenna makes
Hi All, I find this all so laughable!!!! I drive a 4 element SteppIR at ~60', by various radios and, at times, an Alpha 87A, and I call tell you all from first had experience it is a WMD -- Weapon of
Gary. Good points. We'll just have to wait and see. If we see massive failures in 5 years, there will be a class-action suit against FM by angry amateurs who will allege that Mike knew the design was
Why does my new HDX-555 have a double pulley on the tower when only a single pass of the lowering cable is shown on the instructions for the TRX-80 tilt over accessory? I have set it up to use the ri
Hi Folks! For reasons I would rather not recount, I have a bent mast. I ordered a replacement from HRO - a USTowers M-20R 2" O.D. x 20' reinforced galvanized mast - listing at $259. Turns out the shi
I thought so too. I have an antenna controller that I built based on a microcontroller but it understands multiple antennas for the same band, remembers the last antenna I was on when I return to a b

I have three very large 'egg' insulators for sale. These insulators measure 5-3/4" long, 3-1/2" across and have 1" holes to accomodate guy cable. They weigh a total of 11 pounds. One of them includes
Hi Roger! I helped a friend put up this same antenna. We mounted it on a crank-up when it was cranked-down so I suspect the heights are similar. We had a devil of a time tuning the 30m portion and it
I seem to recall reading about some rubber-ish shims you could use - extra grip + slight shock absorption on start/stop. Pinning isn't my favorite thing - I'd rather have to re-orient a mast than rep

Attach a shunt wire somewhere near the top of your tower. The lower end of this wire should just reach the ground. Connect the lower end of that wire to a clip lead. Wrap the clip around the coil of
The other day I saw an ad for an RC truck on the Discovery Channel. Part of the ad shows some kids playing with it in a driveway and for an instand you can see what looks like a tribander on the hous

I am trying to locate Dave Arruza W1CTN to complete an ebay transaction for a large coil. He has failed to reply to several emails and a phone call. Sorry for the bandwidth but I'm grasping at straws

I need some recommendations as to how to run the cables from my tower.... I have fsj4-50b to run, some surplus CATV stuff that's about an inch thick, rotator and antenna control, a cat-5 cable for so
The 'low voltage' and regular conduits would be separate... Do you have any electrical code issues? (like, do you have to meet code?) If you do, that will substantially affect the alternatives. For i
