I ran the cables at the top of the tower through a piece (~4') of pretty heavy garden hose and attached the hose in several places to the tower top with a large radius bend. They come down from a sta
Let's see; at ~$40,000 for a small city lot, the Vee beam using perhaps 15 lots (?), that is about $600,000--lots of pennies!!!!!!!!!!!!! k7puc _______________________________________________ _______
Unbelievable prices but I believe they are asking prices rather than "going for" prices. According to Amazon, collectible includes signed copies, out-of-prtnt copies, and like new copies (I think). I
I agree that the two books would be nice to have (if you don't?) but I doubt if they will be of much help in your case. There are just too many variables. I suggest getting an antenna modeling progra
I have a Force12 2 el 40m yagi that I purchased and then decided to go with the Steppir Monstir yagi. The Force12 EF240 has never been assembled or even taken out of the shipping container. The EF240
My EF240 posted for sale is on the way to its new owner and his payment is in my bank. Hopefully there are two happy hams--I wish that I had more to sell for that price as several more offered to buy
I suspect that the radial system doesn't "prevent" current flow but instead shunts a large portion of it. I think further discussion would be helpful here. I suspect that in all cases except an infin
Is there a diagram or explanation of the wire for the 80m antenna option on the db36? I wonder if it can be put on a crankup tower and also what the radiation pattern is like? k7puc _________________
I hope that some there will come a posting in simple terms about the purpose of a thrust bearing? It seems to me that the "axis of rotation" for a mast mounted thrust bearing is vertical, thus the de
I would like to get in touch with anyone that has experience with the subject antenna or knows of someone that has had experience with it. I purchased it several years ago and then purchased a Steppi
Please provide us with as much detail info on those signals as you can: 1. Where do you connect the scope ground? 2. What is the time duration of the pulses? 4. Are those pulses only during switching
Yes, I agree that the original poster was probably referring to the end result. That is why I mentioned "misstated" at both the beginning and end of my posting. However unless usage of terms has chan
Some responses to my posting illustrate the benefit of multiple postings on the same subject but analyzed from a different point of view. One point of view on resonance (actually reactance) was from
I don't have any standoffs except the one at the top of my LM470. At the top I used heavy garden hose around the coax & rotator feed in a large arc to distribute the force. The coax & lines drop easi
I have a question on overheating winch brakes. I replaced the K1550 on my LM470 tiltover fixture with the K2550 and that eliminated the very loud squealing when tilting the tower down. I also added t
The short answer is that I had a U-shaped bracket made that would snug fit over the outside leg of the tower and tightly hold it in place by squeezing the bracket with two bolts. The bracket was made
I have had a 2 el steppir at the top of the second section of my 70' crankup which puts the 2 el at about 37'. A steppir monstr is at the top at 72'. My reason for the using the 2 el was to be able t
