How long is a G5RV Jr?
How long is a G5RV Jr?
G5RV JUNIOR is a HF Wire Antenna, covering 40m to 10m bands. It’s overall length is 51ft 15.55 meters, Ladder line 15.6 feet 4.77 meters and should be fed with good quality 50 Ohms coaxial cable (recommended feed length of 45 or 90 ft).
Does a G5RV need a BalUn?
Though Loius Varney described a number of configurations of the G5RV, most amateurs erect a G5RV that has either a flat-top or inverted-v dipole, fed with a length of parallel wire transmission line and then an indeterminate length of coaxial transmission line to an ATU / tx with or without a balun at the coax to …
How high should my g5rv antenna be?
Ideally this dipole must be placed over 10m high. The antenna can be fed by any convenient type of feeder provided always that a suitable type of antenna tuner is used.
What is a Carolina Windom?
The CAROLINA WINDOM® was the first antenna to take advantage of ‘VERT™’ (Vertically Enhanced Radiation Technique). VERT™ (Vertically Enhanced Radiation Technique) is a radiating feed line technique that produces a controlled, low angle vertical radiation pattern. The effect is absent from most ordinary antennas.
How long can a long wire antenna be?
Long-wire antennas require a length greater than a quarter-wavelength (λ/4) or half (λ/2) of the radio waves (most consider a true long wire to be least one wavelength), whereas random wire antennas have no such constraint.
How long is a Windom antenna?
The normal Windom is described as having a 1/3 length leg, and a 2/3 length leg. In other words an 80-meter Windom 137 feet long would have one leg 45.667 feet long, and the other leg 91.333 feet long.
What is a Windom?
The Windom is a horizontal wire fed off-centre by a single-wire non-resonant transmission line. It is named after L.G. Windom, W8GZ, who described it in September 1929 QST. The goal of this original concept was to make a simple antenna that could operate on multiple bands.
How long should A TV antenna last?
Under normal conditions, TV antennas typically have a lifespan of 10-15 years, after which time it is common to experience problems such as dropouts or small square “blocks” on the picture, known as “pixilation”.
How long should my dipole be?
When determining how long to make each leg of a Dipole antenna, dividing the frequency in MHz into 468 will give the overall length. To find the half wave, divide that number by two. This will give you the length of each leg of the antenna.
How big is Windom?
