OmniOmani, Mini, Mono, Oman, Omen, Omanis, Min, Mon, Mani, OMB, Ono, Omit, MN, Mn, Mona, ON, Om, On, Domini, Odin, Olin, Orin, Anni, Emmi, Omens, Ami, Oms, One, Own, Uni, Amii, Arni, Omar, Oona, Agni, Oman's, Omen's Antenna [1] have a broad propagation field, designed to be
basically uniform in all directions.

In practice, this is not spherical, but often more Smarties [2]-like,
wide, but not high. The higher the gain, the flatter the Smarties [3].

Typical gain of omni'sOman's, Omanis, omen's, Min's, Mon's, omens, Mani's, Ono's, amino's, ominous, Amen's, Mn's, Mona's, monies, Armin's, Domini's, Ermin's, Odin's, Olin's, Orin's, amine's, omnibus, Armani's, amines, Ami's, uni's, omits, minis, Mons, Omani, onus, amens, oms, ones, owns, unis are in the 3dbi-15dbi range.

One common and relatively easy to construct type of omnidirectional
antenna is the CoaxCollinearCoax Collinear, Coax-Collinear, Coastline, Quasilinear, Catcalling, Cackling, Crackling, Joceline, Cajoling, Gasoline, Masculine [4].

Some omni-directional Antenna [5] plans:

* The Slim Jim [9] (not 2.4Ghz)

At this stage, we have not yet seen a homebrewhome brew, home-brew, hombre, Hebrew, Homere, hombres, hombre's omniOmani, mini, mono, Oman, omen, Omanis, Min, Mon, min, Mani, OMB, Ono, omit, MN, Mn, Mona, ON, om, on, Domini, Odin, Olin, Orin, Anni, Emmi, omens, Ami, oms, one, own, uni, Amii, Arni, Omar, Oona, Agni, Oman's, omen's with the
combination of decent gain and a suitable radiation pattern (the
Smarty is tilted up rather than be level) for the >1km links we're
trying to make at MW. Any results to the contrary would be much
appreciated!

If you want to buy a commercial omniOmani, mini, mono, Oman, omen, Omanis, Min, Mon, min, Mani, OMB, Ono, omit, MN, Mn, Mona, ON, om, on, Domini, Odin, Olin, Orin, Anni, Emmi, omens, Ami, oms, one, own, uni, Amii, Arni, Omar, Oona, Agni, Oman's, omen's antenna, D-Link sells an 8dbi
outdoor omni, as does RojoneRockne, Rhone, Rooney, Jone, Rejoin, Roxine, Regine, Recon, Roanne, Roxane, Romona, Rosene, Redone, Rezone, Rooking, Joane, Jonie, Ronnie, Rookie, Crone, Crooner, Krone, Rejoined, Jon, Ron, Rowen, Roanoke, Rowney, Croon, Regen, Forgone, Jane, Joni, June, Rene, Rona, Cone, Coon, Gone, Goon, Roan, Rook, Rune, Coroner, Groyne, Trojan [10]. That is, if you missed out on The
Incredible Bulk purchase of a few squillionscullion, squalling, scallion, sculling, scullions, Quillan, gillion, squealing, zillion, stallion, gazillion, squallier, scullion's lately. Higher gain ones
are available from several US vendors, but the propagation pattern
starts to get kinda thin and often has quite a deal of downtiltdown tilt, down-tilt, dentist, Donalt, daintily, dental, Donald, download, daintiest (which
is great if you're on the top of a hill, not so great otherwise). If
you really need that kind of gain, maybe you should consider a
YagiAntennaPaginating, Yanaton, Gargantuan, Argentina, Canteen, Quintana, Quintina, Ugandan, Gaunting, Yucatan, Canton, Cointon, Quintin, Quinton, Canting [11] or ParabolicAntennaParabolic Antenna, Parabolic-Antenna, Promulgating, Predesignating [12].
