Anyone know where I can find suitable rotor cable for the OR2800 rotor (2x 12ga, 2x 18ga shielded pair). I see The Wireman has it. Anywhere else? Eric K2WD Sent on the Sprint® Now Network from my Bla

Any recommendations on the best way to shine up a yagi that has been lying unassembled under weeds and leaves for a number of years? I just picked up a used M2 20m yagi, and want to "shine it up" a
Fortunately, the previous owner used a liberal amount of Penetrox on all the element joints and boom joints. My main reason for wanting to "shine up" the overall appearance is to make it look a lit
Good afternoon, I installed an OR2800 dc rotor yesterday, and ran into a few issues. After performing the calibration routine, I tried to rotate the rotor one full 360 degree rotation. However, the r
Thanks for all the replys, both direct and thru the reflector. I have been able to successfully rotate the rotor 360 degrees all weekend at speed setting 5. Then, as of this morning, I decided to t
Anyone using the US Tower IV-16 inverted V bracket? I have one installed here, and have already seen it spin around approx. 90-120 degrees while rotating the antenna stack, and it almost yanked
After deciding to discard my trusty old W2AU 40/80m trap dipole which finally failed (trap of balun, not sure yet), I constructed a new 80m inverted V last evening. Works great on 80m, but I would li
I think the biggest problem with this design is the fact that the dipoles are pulling downward instead of horizontally, thus causing it to bind with the mast no matter how well lubricated it is. Aft
I hope this is ok with the moderators. If not, please delete and accept my apologies. For sale: HyGain Discover 7-3 3 element 40m yagi. Brand new, but out of the boxes. I started to assemble it, but
Hi Phil, I have used a lot of the Shireen RFC400 cable, a few thousand feet to be exact. For the price, it can't be beat. As good as Times LMR400 or any of the other knock offs. I have six runs goin
Good Afternoon, I have a few questions regarding my 40-80-160 dipole installation. It resembles something in between a parallel and a fan dipole. I have a 1:1 current balun at the end of a piece of L
I've purchased and used a considerable amount of AllRFCables (Shireen) RFC400 cable. Over 10k feet so far. In fact, I have almost 2000ft in service at the moment at my own qth. Ten runs from the sh
Wow, I just ran some numbers thru this online utility, and the results vary wildly from the older ARRL Antenna Mast Analyisis Excel sheet I found online a year or so ago. Can anyone tell me the corr
The Unidilla trapped dipoles are hard to beat, AS LONG AS you don't run over 800-1000w PEP. I installed my 160/80/40 Unadilla trap dipole as an inverted vee last fall. It worked great the first hour
Good Morning. I recently installed a US Tower HDX589. I also installed a number of 3/4" 10ft ground rods. Then cad-welded #2 stranded copper wire to the rods. I am now trying to determine the best w
How about using the aluminum lugs? Would that be ok between the copper wire and galvanized tower metal? Eric K2CB NEVER let copper come in contact with galvanized metal. Always use a transition meta
Ok, then what is the best method to connect a #2 stranded copper wire to a galvanized steel tower? Eric K2CB Nope, aluminium and copper hates each other... Actually, aluminium is in relatively good r
I am using a number of Polyphaser units in line just before my cables enter my home. I have opened them in the past to discover that there is nothing more than a surge device from the center pin of t
Good afternoon, I recently suffered a lightning strike to an antenna on my tower, and my OR2800 now indicates 16 ohms on the two motor wires (pins 1 &2), which looks normal. However the reed switch i
