Aloha and Mahalo to all who responded with the QTH info about R1ANF, down in the South Shetlands at a Russian base there. Also very pleased by those who have pointed out that the HF bands are little,
No, but the most powerful are atop many hotels, especially out here in Waikiki!! Have often wondered how many tourists are aware of the immense amount of RF surrounding them at, for example, the Hilt
To those interested, Well, they are up, at least as they will be for awhile. I am satisfied that the four are operating. But the angles between wires could be wider, and more even; I wish that I coul
Aloha, No, they are not the same. The Yaesu uses 90 mm hole diameters on a circle of a diameter of 119 mm, of all the crazy dimensions!! We estimated the center of the old Tailtwister pattern, then u
Status, all tangled in the way too rapidly growing tropical vines!!!?? And these four beams must be up and operating in two weeks, or will miss their use in the CQWW. Unfortunately have waited too lo
Aloha, One of the OT's out here, Sam, KH6AFS, at Hilo Town puts out a Snake antenna at many of the field events here. Last was on 9/27 for a QRP outing. Anyway, the purpose for him is to listen to ma
Rcv'd many comments about the snake, some follow: "I had no luck with a snake antenna." "Yes, that antenna does work, but you have to be careful because some lengths will show you the same thing at t
What follows is long, wordy!! Guess they win. The V-beams will not be up for the CQWW. Am sun burned, and just don't have the energy to scramble enough to get all the wires "just so", or even any oth
Ok, so what is special about these lengths of wires for Beverages and long wire antenna legs? I see W3LPL, Frank, specifying same for beverage lengths, and Lloyd Colvin, way back in 1956, specified 5
Aloha, "I've had Paul's XMatch now for many months; am super pleased with it!! I also have, for my V-beams, planned for set-up as soon as the darn trade winds calm down -- up to 36 mph this afternoon
Aloha Carlos, I have 160, 80, 40 and 30 meter parallel dipoles, all fed by a single 72 ohm twin line. The ends go down to various trees, usually with rope to complete the span, and a couple to push-u
Aloha from Hawaii, I hope the following will not cause me to be de-listed from the reflector. However, we need to consider the situation that may be developing in the FASC committees of both the ARRL
Aloha from usually windy Kauai, If you go low on the palm, there is little swaying motion, some. Palms have, not a deep, but a very wide area of root coverage. They spread a carpet of roots, perhaps
Yes, it works fine; and is described in both the 16th and 17th editions of the ARRL Antenna Book, Chap 24. In the 16th edition see page 24-21 and Fig. 27 of that chapter; in the 17th edition the same
Depends upon how you connent the parallel runs of coax: to quote from the ARRL Antenna Book, 17th ed, pg. 24-18: " Shieled balanced lines have several advantages over openwire lines. Since there is n
double. In at round impedance. But Ronald, the R in R+/-jX in the coax cable's characteristic impedance is what is 50 ohms, not the loss resistance of the wire! The R which is 50 ohms in the characte
Hi Pete, Well if the two transmission lines are identical and everything is matched, then one half of the RF current is going to flow in each line. Note that to be matched the source and load impedan
Aloha, Well, with apologies to Oscar Hammerstein, 2nd. "When I was a boy, what waw what was what, What was so was so. But now I am a man, and some things are nearly so, and some are nearly not!" And
Well, here are the results I just got from my 950SDX and 1000D. Used WWVH as a constant carrier source: about 25 miles due West from my QTH, with a slight ridge between. WWVH uses dipole "curtains" t
Oh, oh, here we go again. When I was in engineering school, the definition of dB was that it is 10 times the log(base 10) of the power ratio. For voltage change ratio in the circuit, it is 20 times t
