No-corrode QuietFlex™ Wire OmniLoop is a closed loop antenna that's a full
wavelength long on 160, 80 or 40 meters. Here's why an OmniLoop™ may be just the
antenna you need: OmniLoop is an efficient broadband radiator, even when low to the
ground. Second, OmniLoop has easily tuned resonance's on all harmonics of its fundamental
frequency. A dipole by contrast has easily tuned resonance's only on its odd harmonics.
OmniLoop starts out with 1.2 dB of gain over a dipole on its fundamental frequency. Gain
is higher if the antennas are less than a quarter wave off the ground while OmniLoop stays
efficient. Also, OmniLoop's gain over a resonant dipole increases with increasing
frequency of operation, so when used on its harmonics, OmniLoop's signal advantage over a
dipole increases. For a horizontal OmniLoop, that's not the end of the good news, because
as frequency rises, radiation angle drops lower and lower, producing increasing DX results
that can rival a multi-element beam mounted on a 100-ft tower.
And OmniLoop™ is forgiving. Perfect symmetry is not essential.
Just hang it in the configuration providing the greatest enclosed area. What this means is
that OmniLoop can be strung up in unusual places and still perform well. Treetop
suspension is ideal, but you'll be surprised how well it works just lying on the roof
where nobody sees it. Even stapled to a 4 ft wooden fence or under ground in a basement or
parking garage OmniLoop is startlingly better than alternatives. And OmniLoop is easy for
your tuner to match, because its feedpoint impedance never gets as high or low as with an
antenna that has free ends. Even a 40 meter version can give you full 80- 10 coverage. All
OmniLoop's provide gain and multi-band coverage. Choose the size that fits your space. Then
select coax feed or balanced airline feed version.
Coax feed has a custom drip-shielded SO-239 coax connector.
Use your own coax or order an appropriate feedline. A balun isolated feedline is
recommended.
OL160 OmniLoop coax feed: Length 560 ft. Space Required:
Delta--187'/leg; Quad/Diamond--140'/leg; Penta--112'/leg Loop resonates on 160 meters and
higher amateur bands. Radiation is omni-directional on all bands when mounted horizontally.
Gain increases with frequency of operation, while radiation angle drops, giving
progressively better omni-directional DX performance from 80 meters up. OmniLoop™
rejects man-made electrical interference, natural static, and charged particle noise for
exceptionally quiet reception on all bands. OL80 OmniLoop coax feed:
Length 290 ft. Space Required: Delta--97'/leg; Quad/Diamond--73'/leg; Penta--58'/legLoop
resonates at 3.5 MHz and all higher amateur bands. Can be loaded on 160 meters at slightly
reduced efficiency. Radiation is omni-directional on all bands when mounted horizontally.
Gain increases with frequency of operation, while radiation angle drops, giving
progressively better omni-directional DX performance from 40 meters up. OmniLoop rejects
man-made electrical interference, natural static, and charged particle noise for
exceptionally quiet reception on all bands.
