Bob. A launching gun? Sounds dangerous. I discovered a simple wire deploying mechanism about five years ago. It is a softball with a screw eye installed and 100 feet of twine. _______________________
oh! A grenade launcher! I bet you could rent a cherry picker for a month for what that contraption would cost (including medical bills and lawsuits). _______________________________________________ _
I am a LOT unconvinced. I was waiting for someone to finally figure out that the metal pole being discussed could actually be a vertical antenna. _______________________________________________ _____
Well, lets see, if you find that the trees do not have much effect we can all rest easy and get back to playing with ham radios. If you find that trees do have a big effect are you going to move out
Interesting thread. Loss (whatever you might think about its significance) can be completely eliminated by doing away with the connectors. Just grab some of that 'no-loss' coax I keep hearing about a
That is an interesting observation. Also interesting is the fact that the lug is copper. Unless the plate is also copper this whole setup is doomed to failure from galvanic action. Just because somet
I am pretty sure that most any metal will rot in the ground eventually. After all that is where it came from. However dissimilar metals will rot quicker even if they are protected. I would use copper
This is the best argument I have yet heard on why the best available may not be good enough. If it requires an exceptional understanding of the physics behind it to understand why it is not providing
Thanks for the explanation, Pete. I guess I did not fully understand what HFTA was all about. Now that I do, I am not convinced it is entirely useful, at least not to me since I don't have the resour
Sounds to me like you need to find a better location for the event. _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@co
I Believe most mail prorams allow filtering on subject line info. At least mine does. I never even see mail that has no subject. Such nonsense gets trashed immediately. Also, today you can buy 500gig
While it is interesting to speculate on how spam gets delivered, I find it even more interesting that there are so many folk who think that pissing people off is going to gain them business. I mean h
Smart move, Mike. Sometimes we forget that the climber may weigh in at four times the weight of the antenna. A tower that can comfortably support a 50lb beam may not do well with a 250lb top load. __
Pinning the mast to the rotator is a sure way of preventing mast slippage. It also puts you at risk for rotor destruction if the wind load becomes overly excessive. Since there is no good way of pred
This 'problem' has the obvous solution of ' just get a bigger balun'. Then, instead of agonizing over test methods, we can operate the radios. Use two cores instead of one and forget about taking tem
Good point. Sounds like a good reason to build your own. _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.co
My thought exactly. Even so I also have some junk from the mid 50's. CW only. It is nice to know I can still use it by hooking up my cheap old low pass filter. _______________________________________
From that information can I conclude that if I have a decent, short length ground connection and a feedline that is an odd multiple of quarter wavelengths long, I don't need a CM choke? Consider as a
The trick is figuring out what is proper. I guess if it works, its proper. I have a basic question regarding CM chokes. My understanding is that you make a choke by windng the feedline around a form
This is an interesting thread. Lots of new high tech materials to choose from for making antenna insulators. While we are considering the various attributes of these promising solutions lets not lose
