I agree - I have never read this and when I talked to Universal last year they just told me any weight over 200 pounds can bend the rungs, so they didn't recommend a climber with gear exceeding that
I'd like to know how you know created a 402CD model that you know is accurate? Which NEC version are you using? -Scott, WU2X _______________________________________________ __________________________
Ok, the only reason I asked was I had asked on several reflectors/forums how one could correctly account for element taper in NEC2 when it was loaded, since Leeson's method cannot be applied. Does an
How do you define resonance? My dummyload on 80 meters shows an impedance of 55 + j0 Ohms, it doesn't get anymore resonant than that. -Scott, WU2X _______________________________________________ ____
Hey All, I put up an Array Solutions K9AY RX Antenna this summer for 80m/160m. The antenna is placed over rich marshland (freshwater). In fact we've had so much rain that its nearly over a pond. I ha
Hi Jerry, Easy enough for me to try, My transmit loop is hooked to a switchbox that will ground it when i switch it off. Good point though, the length of the feedline will determine if the transmit l
Hi All, I just made 8 turns through two 2.4" #31 cores with the coax (RG8X). at the feedpoint I have some #31 split beads I will clamp onto the control cable (when it stops raining!). The coax is a 1
Yes - I second U-Ship. I used this to ship my HDX572. -Scott _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contestin
Hi Guy, Just out of curiosity, what is your familiarity with antenna computer modeling, with a program like EZNEC or 4Nec2? I wonder what is keeping people away from software like this. It seems many
Since 1998, companies are now permitted to advertise gain figures in ARRL publications: http://www.arrl.org/ads/antenna/ -Scott, WU2X _______________________________________________ _________________
Hi, If you have an accurate Force 12 C31XR NEC mode (eznec or nec), including taper schedule, I would appreciate if you could email the file. Thanks in advance. -Scott, WU2X _________________________
I don't think these "farm duty" electric motors are designed to sit out taking the full force of the elements. I keep my the entire motor/gearbox/limit switches and drum covered at all times will pla
Hi All, I apologize in advance for having to ask this question. Has anybody be in contact with Cubex/Tennadyne since December? I've been trying to order quad spreader hubs since December. No answer o
I also put together a 18 foot boom/ 8 element NEC4 model using the ARRL LPCAD program. My gain figure for the LPDA were a little higher (5.5dBi), but I agree with what is shown here. Also note, its n
So you are lengthening the boom length to 20 feet. I thought the discussion was comparing a Tennadyne T8 to a 3 element Steppir. Does the Tennadyne T8 use a parasitic director for 10 meters? Sure, if
This is true, but the cool thing about the LPDA is the gain *and* F/R go up. My point about the 36 foot long boom is that you truly have the gain of a 3 element yagi over the entire frequency range a
Yes, this was posted a couple weeks ago. Excellent article, excellent antenna, model file is on this site as well: http://www.realhamradio.com/Log_Periodic.htm -Scott, WU2X __________________________
Yeah me too! I read that they are nylon air braking tubing. It looks like three concentric pieces. I need to make up a bunch of them for myself. If somebody has one in their hands it would nice to kn
Do not make this assumption. As has been said before, use uship.com to get some bids on moving a tower. I contracted a guy with a 24' gooseneck trailer and a winch on the trailer. Easy to load. Guys
