Indeed. But if the longer radials put your wire in your neighbor's back yard, or run out into the street, or into your basement, then radials need to be abandoned as your counterpoise solution. That
Let's hypothetically suppose the tuning is not there. Then the program itself is just flat wrong and miscalculating in some areas. I'd far rather blame it on tuning than mis-coding. It really works q
There is a bit of explanation and clarity in BL&E regarding standing waves on radials that does not show up until page 781 and figure 42. ** Emphasis added. "The current in the buried wires **for an
Well, I *don't* understand why people are upset about this. The K4VV crowd operated a station in Virginia that had all it's antennas and all the RX and all the TX on one local property. They reported
The short answer is that a foot of snow on top of it will affect it terribly. The long answer is gawd-awful. Don't ask any more if you don't want to know. 73, Guy _________________ Topband Reflector
Not based on my experience with BOGs and LOGs under significant snow, or too many seasons of falling leaves, or both. One thing that happens is whatever original BOG tuning, setting up good f/b, done
Having lived in the Newburgh area, I have to object again to this report that I have tried to debunk before. I have earlier communicated this objection to Mr. Fry which he chooses to ignore. Given th
The Brown, Lewis and Epstein study (BL&E) was most likely done over very uniform, and over pretty good dirt for RF. I would trust your measurements as far more typical of ham circumstances. A few yea
"Laying on the ground" could mean anything from laying directly on dirt to top of the grass 5 cm above the dirt. That is a wide swing in VF. 73, Guy K2AV _________________ Topband Reflector Archives
These kinds of results are like my walkabout-on-the-beach results with my Elecraft K2/10/battery plus short antenna. I was listening during the IOTA (lots of stations) to 40m CW signals which should
front property is better than a location inland about a mile or so on a ridge overlooking salt water for HF. ... I understand the theory that verticals literally in or on the water have a huge advant
Luis asked me to edit and pass this on. He has been having some problems with email. 73, Guy -- Hi Topbanders, This is a summary of my first two months of 160m activity from Ecuador: More than one th
Five years ago, in the general Raleigh area, a number of us did exactly as you propose. We all used as standard a 151 foot (46 meters) dipole of insulated wire laying on the ground, spreading out for
One way to move up the "sweet spot" on a BOG that has been "mushed down" is to go to the center of the BOG wire and carefully pull the wire up from its mushed down position a few feet at a time. Pull
Those would be transmitted signal strength concerns. On the receive side, if one ever listens on one's transmit antenna, the feed coax shield is a potential path for RF noise from the house. Any nois
Hi, Max, and anyone else out there trying to make antennas with an SWR meter. Not knowing the separate resistance and reactive components and the sign of the reactance surely do make it hard to figur
Apologies to Max, however... Max's second post came up when I posted my blurb on getting a graphing analyzer. Sorry, Max. However... In the years of correspondence about 160 meter L's over an FCP, co
Models of BOGs in NEC 4.2 show less sensitivity to termination resistance than to electrical length. Practically the far end ground will exhibit a stubborn variability that makes any accuracy in the
Hi, Kirk, A multiband antenna that actually works is actually a difficult thing to get right. We have a collection of them that do work, but they have gotten to us through a process. The original guy
Midway between 25 and 55 is 40. Midway between 310 and 350 is 330. Rotating counterclockwise 10 degrees from the 45/135/etc common USA settings would give you NE and NW pattern centers at 35 and 325.
