In my part of the country, upstate NY, Penetrox seems to be a favorite for use on AL tubing and any electrical connections. I've had it on some places, including exposed to the weather, for more than
Keep in mind that on 75/80 meters a pennant, flag, or ewe will only have a "gain" of around -20dbi. so another db or two of loss due to miss match will hardly be noticed and certainly isn't going to
Al - No problem. Easy to do on such a busy thread. I just like to encourage the use of flags and pennants. They certainly are very effective rx antennas. I've made a system using two four direction p
One more note on the pennants. Based on my observations in the broadcast band (actually changing ststion when switching directions), using a total of 70 feet in the loop, I wouldn't hesitate to go do
Hi Jim - I'm sure that each installation is a little different. My 7/8" comes to the house slightly undeground then through a plexiglass cellar window pane ending with a 7/8" to UHF connector and RG-
Unless you're really crazy about climbing why not start out by opening things up where the feedline goes up the tower and look up the tower with the analyzer. If you're lucky and it looks good then t
BruceYou might want to consider that there are other ways than running guys straight out to anchors to guy a tower. Take a look at sailboat masts. These are obviously special cases and would need som

I think that Cebik's deal with 44 feet was to use it from 10-40 and keep the lobe splitting to a minimum on 10. If you want to play on the cmputer you could look at putting an about 11 foot stub, wit
RE your exact tower location - Small handheld hikers GPS units that give Lat. and Long. can be had on eBay for cheap. I found several Magellan Blazer 12 units in the $25-$50 price range . They were a
I wonder how many tribanders are out there at 40-50 feet either strapped to the side of, or on side gates, on 75+ foot towers as a result of HFTA, or were put there as a result of observed need befor
Yes, making use of HFTA can still be a PITA, but the development is still in relative infancy. Remember when Jim Lawson / W2PV did his early yagi analysis work on a one off basis on big GE computers,
Jim - Even at a half an hour it's a real bargain. I would guess that many in the group would climb all over that opportunity and all in our group would thank you for your effort. It's what makes this
Unless you're a Sam Harris disciple (if it stays up more than a year it was over designed), it's hard to be too cautious when you consider the possible combination of factors such as ice and wind, re
For any who might be a slow whited as I, don't even think about opening any of the "no subject" postings that have been showing up. Too bad they can't be filtered out. I opened one a couple of weeks
Why make it so complicated? Why not just use hose clamps either on the barrel or on the connectors to clamp the "joint" to the tower leg, using lots of Penetrox on the mating surfaces and being sure
The antenna that Mike is talking about, with the LP feed cell, i.e. the TH-11, might have been considered in the "Thunderbird" family (certainly lots of common hardware), but wasn't introduced until
Hi Grant - I believe that your TH-7 is a tribander with a dual driven element to give broader band coverage. The TH-11 definitely has an LP cell that covers all of 10m-20m, plus reflectors and direct
