I tried posting this query to CQ-Contest but didn't get any substantial responses so I thought I'de throw it to the real antenna guys to see what you had to say. I'm looking for an 80m antenna (or an
I am considering constructing an array for 40m made of two quarter-wave verticals spaced an eighth wavelength apart using a Christman feed method. The details of this array are discussed in ON4UN's L
Does anyone know how many square feet of antennas a AB-577 Rocket Launcher mast will support and at what wind speeds? What's the most antenna/mast/rotor weight that can be put on top of one? Any info
Is there any reliable way to tell what the "real" height of a yagi is that's on top of a building? In other words, electrically how high the antenna thinks it is. Is there a formula to calculate this
Hello all. Take the following scenario: -A house on a plot of land that's about 10ft above sea level at the most but has no ground level salt water anywhere in the vicinity -The house has a balcony a
Hello all. A few months ago I found an old Mosley CL-36-M six element tribander atop a local tower. The owner said that I'm free to have the beam if I take it down. It has been atop the tower for 20+
How close can a dipole, say the G5RV, and a commercial made vertical, say the Butternut HF-2V be placed so that they will not interact with one another? Does the distance differ depending on the band
Can someone recommend a good climbing belt that is preferably sold on-line. I've checked Texas Towers, ARS, and HRO but no luck so far. What is the climbing belt of choice for TowerTalkians? 73, Nat,
I'm wondering how the Cushcraft R7000 interacts with salt water QTHs. At what distances from the salt water are the benefits of having the salt water as opposed to average ground diminished and by ho
I've noticed that both KC1XX and W3LPL have yagis for 10m-20m going all the way to 200ft high. Are yagis in the 150-200ft range for those bands really all that useful, or are they more of a "few QSOs
Forgive my ignorance on this topic, but I'm wondering if there is a good way to determine exactly how far away the "first hop" is from a given QTH. Is there a constant number that's often used as the
I've been wondering, what is the effect, if any, on the pattern of an antenna if it is radiating in the direction of another antenna? For example, suppose that a station consists of 2 towers spaced 1
I've heard that it often helps the performance of slopers, "Cloud Warmer" dipoles, and low Yagis if one puts radials under the tower (or whatever they happen to be mounted on). Is this actually true,
I believe that you are thinking of N3BB, not W3BB. Some pictures of Jim's station are located at http://www.ctdxcc.org/n3bb/. Hope this helps. 73! Nat - WZ3AR _______________________________________
I would suggest the GRC AB-577 "Rocket Launcher" crank-up mast. It goes up to 50ft, can be erected by one person, and will hold VHF/UHF antennas as well as smaller HF monobanders and tribanders. A C3
