4-Band Vertical Antenna Ground Plane type antenna made of aluminum alloy with an anti-oxidation coating. It covers 40/20/15/10 meters with user tuneable to the part of the band as needed.
The antenna has a single coax cable feed however each band is individually tuned with a low VSWR across the band. Through fine-tuning, the best (rock-bottom) SWR can be achieved on the user’s choice of frequency within the band. The band selection is 100% automatic through the single feed, just switch bands on the radio.
No extra ground peg or radials are needed, the antenna has its own effective counterpoise replacing the need for radial wires.
The VG4 is light, but built to last and is easy to install. Suitable even for homes with only a small space available. Perfect for roof, patio, small backyard, condo, motorhome installation or portable for field days.
The VG4 is rated to 35 metres/per second which equates to 126km/hr maximum wind speed, however in New Zealand severe wind can often exceed this rating and cause damage. We strongly recommend installing 3 or 4 nylon support lines (not supplied) from the upper section of the antenna to the surrounding ground or nearby structure(s) to increase the wind rating. Damage caused by severe wind or lightning strikes are not covered by warranty.
The top loading parallel resonators are used to give the best vertical-element efficiency. End loading of the lower HF band sections (capacitive hats) allow efficient operation with a reduced antenna height.
Various cable lengths, plugs and plug-type adaptors available separately from TECHOMAN to suit your installation requirements.
