He Walked It Up Alone, Then Worked Franz Josef Land
Chris K1LDO already had the 9 ft whip on his 20 ft vertical. This summer he added a 4 ft extension and a tilt adapter, then walked all 34 feet upright by himself. First night: San Diego, Turkey, and Greenland. Since then: Franz Josef Land on 15 meter FT8, and 240 DXCC entities and counting. -
Under The Aurora: Working The World From An Icelandic Shore
From a shoreline in Iceland, under the auroral oval, Jakob TF1CB put a 28 ft Greyline vertical on the air and worked Japan, Kuwait, and Indonesia on day one. His feed system, his winter plan, and what the aurora teaches every low-band operator. -
20 Meter Vertical Antenna: Which Height Works Best?
Every antenna in the line covers 160 through 6 meters. Height does not decide which bands you get; it decides which band you peak on. Why the core line stops at 28 feet on purpose, where each height shines, and how to pick yours. -
LDG RT-100 Remote Tuner: Why We Bundle It
The 125W weatherproof LDG RT-100 lives at the antenna base, powered over the coax, matching 160-6M at the push of a button. Why the bundle puts the tuner where the physics wants it, and when high-power stations should choose differently. -
What Is the Greyline? The Twilight Band That Carries DX
Twice a day the terminator sweeps your station and the low bands open along it. Here is the physics of greyline propagation, the field evidence, and how to be ready. -
Current Balun Vs Voltage Balun: Why The Feedpoint Gets A Choke
A current balun forces equal currents; a voltage balun forces equal voltages -- and on any real antenna, only one of those keeps the feedline out of the antenna. Including the voltage balun's one legitimate job. -
Can I Use A 4:1 Balun On A Vertical Dipole?
A 4:1 balun often makes the SWR meter happier without making your signal stronger. Real analyzer plots from N3EQF show why -- and where the match should actually live. -
The One-Man Flagpole: KQ4DEP Turned Storm Prep Into A Solo Job
One operator, one morning: KQ4DEP installed the tilt hinge solo, grew 20 feet to 24, and turned storm prep into a one-man job in Southwest Florida. -
Twelve Feet vs. Hurricane Milton: KC4OS Still Standing At 120 MPH
Bob Rysner, KC4OS, installed the smallest antenna we make days before Hurricane Milton arrived at 120 mph. His full damage report: a mere baby wind. The physics of why it stood. -
Three Grounds Walk Into A Shack: Lightning, RF, And The Bond Between Them
Ground is three different jobs wearing one word: lightning protection, the RF return, and bonding. Here is the untangling, with the bookshelf open -- N0AX, N6LF, and K9YC. -
The Other Half of Your Antenna Has to Go Somewhere
A wire up the flagpole, a 49:1 at the base, and an SWR meter reading 1:1 -- so why is nobody coming back? Because half of that antenna is missing, and the yard was never going to hold it. The physics, the fix, and one question to ask before you spend a dollar. -
Why Your Antenna Hates 80 Meters
Your tuner says the SWR is fine and the band says nothing. Here is the one equation that explains it, from Kraus and Zavrel, plus what Severns actually measured about radials and why a vertical dipole is a different animal.
