Can someone provide a link to an example of this "better constructed solder type PL259" with the barrel for RG213 size coax? Thanks & 73, Barry N1EU _______________________________________________ __
The F12 C3S (25lbs on 12ft boom) does a great job. If you do put up that 40m dipole at 50ft, I'm willing to bet that it will often outperform the vertical. 73, Barry N1EU ____________________________
I'm not sure if Force12 still uses riveted construction of yagi elements. In any event, I just experienced my first rivet failure on my C3S (great timing, huh?) and would like to avoid repeating this
Unfortunately, it might be a week or two before I can get the AB-577 down to look at the C3S and assess the rivet failure. Before I "just put a new one in", I'd like to know how to avoid having to "j
Yes - one side of my 15M driven element is now the same length as 10M. 73, Barry N1EU _______________________________________________ _______________________________________________ TowerTalk mailing
Thanks for all the advice! What I think I'll eventually do when I get the antenna down, is drill perpendicular holes one inch proximal (boomward) to all the existing single rivets and add a second ri
Sounds great - please share your expertise in lowering the AB-577 in very windy condx, solo. Yes, it's been very windy here. To address other comments, I assure you my C3S is riveted to spec, althoug
Lightning Bolt used to offer a compact 2:1 balun that was described as a "transmission line transformer that is trifilar wound on a ferrite core." Can anybody direct me to details on such a single co
Steve, it was a balun for matching their quads and delta loops to 50-ohm coax and was magically compact (~3in diam X 2in high). Perhaps I need to find one and dissect it. Barry N1EU _________________
I found a LB balun I received about 10 years ago that had the SO-239 pull out of it over time. As soon as I can, I will attempt to route out the potting compound with my Dremel and photograph what li
I chiseled the LB matching xfmr apart and Steve G3TXQ and Joe W4TV were correct. It is a trifilar wound 2.25:1 unun. Evidently LB felt a balun was unnecessary (?). Barry N1EU ________________________
I'd appreciate hearing how folks have effectively grounded their AB-577 military push-up masts. Where/how did you earth the lower frame and how did you tie the mast to the frame? I know that there is
My G-1000DXA rotor came completely unhinged from its GC-038 lower mast clamp and left my 3-el Steppir and attached rotor dangling from the attached cables. It appears that the attachment bolts on the
I should have mentioned that in the photo, the right two shots of the mast clamp show zero damage to the mast clamp itself. The left shot shows the one damaged bolt hole on the rotor itself. ________
Thanks for responding Chuck. I'm on rented property, so I need to use the AB577 and a lower mast adapter type rotor installation. Isn't there any way to prevent the bolts from working loose like they
Has anybody used Nord-Lock vibration proof lock washers? http://www.youtube.com/watch?v=mgwmuZuJ02I Barry N1EU _______________________________________________ ________________________________________
The original bolts are lost now but the GC-038 doc calls out M8 X 25mm long bolts. The holes are deeper - there's still probably a half inch or more of threaded hole deeper than what is broken off on
Yup, I'll go with Loctite (instead of anti-seize) and Nord-Lock lockwashers. I'd also go with a bolt head securing system, but I'm not about to drill bolt heads and I don't see M8 bolts being availab
I'd appreciate troubleshooting help. I just put my yagi back up after repair. My G-1000DXA is rotating the antenna but my control box azimuth indicator just stays stuck in one position. Thanks & 73,
Thanks for the responses - I found wires had broken off inside the rotor connector from stress engendered during a recent "incident". 73, Barry N1EU _______________________________________________ __
