A 46 ft multi band antenna for small gardens that works well on 80 metersMain bands 50 ohm) are 80m / 40m / 30m / 17m / 15m / 12m other bands

A G5RV modified to fit into a small space. Although a compromise, it performs well. Spacers made from glass fibre sheet cut into strips

model current distribution a ta heigh to of 8m connected to a 50 ohm source via a4.55m matching section of 300 ohm transmission line

The G5RV is a global antenna that has many friends, but also their critics, the following remarks should bring a little more light around the G5RV

About 102 feet long, it was fed with 30-feet of 300-ohm transmitting type ladder line

I bracci terminali possono essere istallati o paralleli al terreno oppure a v invertita

it has been assumed that it is generally possible to erect the antenna at an average height of about 10.35 m 34 ft which happens to be the optimum radiation efficiency on 160, 80 and 40 m bands for any horizontal

Mr. Varney's G5RV version used open wire 600 ohm feed line all the way to the transmatch instead of the short section of 450 ohm window line and 70 feet of 75 ohm coax that most of us know today

The G5RV, with its special feeder arrangement ladder line, is a multi-band centre-fed antenna capable of very efficient operation on all HF bands

The full size G5RV antenna was not designed as a half-wave dipole on the lowest frequency of operation, but as a 1 1/2 wave centre-fed long-wire antenna on 14mhz, where the 34ft 10.36m

L'antenna è composta da 2 bracci dove la lunghezza totale è di 27,5 m

Simply insert a choke at the end of each strand and follow it with 2.5 m of any wire; chokes have no influence on other bands

Specifically designed dimensions allow it to be installed in gardens and other open spaces to accommodate a reasonably-straight run of 31.1m 102 ft for the

Using ladder line as a transformer is not new by any means this antenna in the 102' length is designed to perform well and offer multi-band operation while offering the ease of using coax to feed it

The G5RV is an easy-to-build 80-10 dipole requiring no traps, all bands are covered, including 30, 17, and 12

This antenna does not resonate anywhere, except that it gives an average output over 10, 15, 20, 40, 80 meters

Levy,le sue dimensioni sono 15,54 metri per i due semidipoli e 10,36 metri per la piattina bifilare a 450 ohm, g5rv,rispetto alla levy ho solo fatto alcune modifiche

The basic G5RV antenna measures only 102 feet across the top for 80 thru 10 meter operation, and is fed at the center through a low loss 34 feet feed-stub

The G5RV article, the antenna has been designed as a symmetrical, center fed dipool, with long-wire behavior on the 20 m. radio-amateur band

Connecting the conductors in this way is is supposed to provide linear loading somehow, running

on the following bands i use a home-made, horizontal "half-size g5rv" dipole with watson el-40xc coils plus about 2metres of wire added to each end

The ocfd antenna in not a carolina windom or g5rv type antenna, there is no radiation from any part of the vertical feed line, on the ocfd antenna the balanced feedline is just a feedline

the g5rv is an excellent all hf band antenna, it works well on 3.5 to 30 MHz. it's a dipole, using 14 to 10 mhz wire, fed with laddar line

G5rv multi-band antennas achieve very good swr values on the individual bands without an adapter, the exciting question is how these impedances are to be adjusted to 50 Ω

The dipole elements are 15.55 metres 51.0 ft and the impedance-matching symmetric feedline ladder-line or twin-lead can be either 300 Ω 8.84 metres or 29.0 feet or 450 Ω 10.36 metres or 34.0 feet

Its dimensions are specifically designed so it can be installed in areas of limited space, but which can accommodate a resonably straight run of 102 ft for the flat-top

The interaction between the radiating section and the feed-stub makes the G5RV easy to match on all-bands from 80 through 10 meters with an ordinary low-cost antenna tuner
