The arguments about input vs. output baluns used with antenna tuners makes one wonder if a balun on both would be advisable? 73, Gerald K5GW In a message dated 10/19/2005 3:42:50 P.M. Central Dayligh
Hal, if possible, please give us a few words about hydrogen embrittlement. To me, this is a new concept and would like to know more. 73, Gerald/K5GW In a message dated 11/14/2005 10:15:45 A.M. Centra

I have seen the brake get lazy in these type rotators when they get some age on them. This is mostly a problem with longish cables needing to be made of larger gauge wires. If this is the problem you
-- I've had one of these up for 28 years now. Data is in the Rohn catalog. The main disadvantage is the 130 pound weight limit at the apex of the tower. Four way guying is required, but the footprint
I have an old Hygain catalog showing 42" X 42" X 72" base dimensions for the HG54HD tower. If you need a new base cage I see they are listed as still available for only $289 through Texas Towers. 73,
Hi to all, First, I hope you all have a wonderful Holiday and Merry Christmas. Thanks for the help on this reflector this past year. I am now trying to sort out in my head a simple way to get a rough
Four inch black plastic corrugated tubing is available at Home Depot and Lowes for about 20 or 30 cents/ft last time I checked. It was available in 10ft and 100ft lengths. This stuff has little slits
Further to Peter's comments if there is a beam on top: The driven element of the beam can add considerable top loading to the shunt fed tower. The balun that connects the driven element to the system
After handling literally thousands of 20G and 25G tower sections I can positively state that 20G has seven horizontal and six diagonal braces per side, the legs are made of 18 ga. steel and weighs 32
Rohn has no painted section or at least has not over the past 28 years. The G in their model numbers signifies a galvanized finish. 73, Gerald K5GW In a message dated 3/22/2006 9:46:46 P.M. Central S
Dino, Here is some info to get you pointed in the correct direction: When you try to measure the telescoping tube type capacitance directly it likely requires quite a bit of lead length to connect to
Hi Rich, we cater primarily to ham radio operators. We get very few requests for 65G and are not equipped to handle the long and heavy sections. Once upon a time we handled Andrew cables but the ham
Hi All, here is a bit of clarification on the Big Grip and thimble size issues: Rohn does not make Big Grips; Preformed Line Products Co. makes them and sells them to Rohn. 1/4" EHS uses a BG2144. Al

Here is a golden opportunity for a talented computer programmer! If Polaris makes the rotation as described then it passes right through true north twice per rotation. The needed software will tell u
Just thinking about this question says one of three answers might work here: network for each frequency of interest. The usual shunt feed matching network will likely provide much of the matching cap
A rotator unit this old probably has a dead phase shift motor capacitor in the control box. Over time the electrolyte dries out and the capacitor turns into a resistor. New capacitors are available f

Crank up towers using manual winches do not like to lower when strong winds are blowing. The weight of the sections is not great enough to overcome the binding forces between sections. Most if not al
