GEK - HF Multi Band Endfed Antenna

     While inverted v dipoles are very efficient antennas, they are not the only way to go. Some houses don’t really lend themselves to installing a half-wave dipole. If you only have one support a GEK HF Multi Band Antenna may suit you better. This one does not require the Antenna Tuner to operate. It is resonant Half wave on 80m (3.5MHz) therefore also resonant on second, third and fourth harmonics etc. Due to high impedance feed point; the antenna is less height dependent. You can put it up at 30 or 50 feet in the air without much change in VSWR values.

Various installations such as horizontal, vertical, as inverted V, as inverted L, zigzag etc. are possible.

Each and every orientation have different radiation pattern and different takeoff angel

Non metallic pole should be used in vertical position

Measured VSWRs values could vary with way and height of installation.

Maximum height you put will get maximum results

No counterpoise Required (Grounding recommended)

NOTE: Grounding does not affect antenna tuning. If the transformer box is installed high above the ground, there is no need to route the ground wire from the box, instead just ground the coaxial cable at the entrance to your home or at the station.

Two Models available

1) Hanging type and

2) With aluminum plate , SS Bracket and SS clamps for pipe fittings.
