Davis BuryFlex is pretty darn close to it. It has a very good PE jacket, both for wear resistance, water resistance and sun resistance. Chris KF7P _______________________________________________ ____
Jim/Clay, I have an instruction manual that goes over install, but here's teh condensed version: When you attach cables to each arm, start with the tower at full height with the cable hanging. Mark w
In the amount of time it took you to type out this treatise, you could have called Tashjian Towers, ordered a new base, and then still had time left over to walk into the kitchen and make a nice turk
Also, if you are more concerned with wind speed, these people have some cool stuff, including a wind switch that can turn stuff on/off at a predetermined wind speed (like an alarm! Lower the tower! :
When considering WX stations, some of you guys may find this irritating like I did... but be aware that some WX stations only report the wind speed to your console like once a minute, or once every 1
Agreed...it's scrap metal now. Maybe if you were using 30' for field day or something, but more than that? Nope. Chris KF7P _______________________________________________ ___________________________
I think what he (the author) means is this: A snap-on, without multiple turns through around it, isn't effective at HF frequencies. We're talking about mix 31 or 43 here. If you wind multiple turns a
Oh and another thing: There are so many generic, un-spec'd snap-on's floating around that we don't know what mix they are, and therefore are no good to us. Hamfests are notorious for this. Chris KF7P
A turn = winding the wire/cable through and around the core, has nothing to do with size. Ask the manufacturer. I have no idea what mix they are using or what their target choking frequency is. But
We just went over this less than a month ago. Jim presented the following studies to debunk this nonsense: ** You're looking for a citation on the debunking? As far as the claims on porcupines or spi
Yes...enlarge the holes on the tower base. Die grinder with a roto-file bit(s). Will take some time but removing 1/8" of steel certainly won't weaken it enough to be a problem. chris KF7P Instead of
What gauge did you use, and how did you terminate the ends? Chris KF7P More than 10 years ago, I bought a bunch of this stuff and built wire antennas with it. All broke within a year. I love Davis RF
Sorry, I meant what was Jim doing where he had the failures? It seems like I remember him talking about running the hoist ropes over pulleys and down to 100# weights or something to prevent tree sway
So a lightning bolt comes down through two miles of AIR (which is an insulator), but it won't jump a gap .010" between the sliders on the tower legs? Also, aren't crank up towers Ufer grounded by def
I personally think solid wire is better, but when you're talking about #2 solid, stuff that big gets pretty difficult to work with. It's as big around as my little finger and requires a lot of streng
Hello, All ferrite on my site is 20% off for the next day or two! Also a few other items. http://www.kf7p.com/KF7P/Welcome.html Enjoy, Chris KF7P _______________________________________________ _____
Why dont we permanently retire the term balun and use either choke or "impedance transformer in its place? Chris KF7P Bigger sigh... No its not... it's a choke that many mistakenly call a Bal(anced)U
Yes.the DRF-400 is really a hot ticket right now, really good specs, lower loss than other 400 imitators, with a ridiculously tough jacket that you can bury, run through ponds, etc. Special buy, .75/
