Alguien tiene algún esquema o a probado alguna antena tipo trébol para la banda de 6m 50MHz, en posición horizontal que es omnidireccional...

similar a "Big Wheel Antena 50/144/433 MHz"

O algo similar a la antena circular, cómo un dipolo plegado, con los extremos apenas tocándose entre sí similar a la antena antena Halo

Thank you for the inquiry. These antennas are currently unavailable. We anticipate being back to full time amateur production in late August.
Omniangle pricing:
OA-50 $99

SK-50 $54
SK-144/SK-222 $44
SK-432 N/A

Allow $10/ item for UPS shipping


These antennas are an entirely different design from the classical
shortened half wave loops.
Omniangles use an electrical length LONGER than a half wave and an
isosceles triangle shape to synthesize a perfect omnidirectional pattern (within +/-
0.5dB). The square and round loops have an elliptical pattern with front
to side ratios of 5dB and more! We hope to soon have plots taken at the
Florida Motorola anechoic chamber of all of the commerical "omnis" on our site
Our largest clients are commercial and military. As a result, all of our
hardware is stainless, all metal surfaces are either polished or
jitterbugged. The connectors are silver/teflon. The Omniangles are the
only commercial series that have a built in balun and do not require an
insulated mast in order to prevent mast/feedline radiation.

Payment via PayPal (par@parelectronics.com is our account #) or prepay by
check.
PLEASE NOTE: We have suspended Omniangle production indefinitely while we tend to our military and aerospace clients.
Thank you for your patience. If you cannot wait, and we
understand, the only other commercial omni we can recommend is the M
Squared. Although they suffer from the non-omni pattern and balun issue,
they are very well machined and built. Others we have had on our test range were of very poor
build quality and poorly documented.
