BULLET4006 Antenna
Off Center Fed (OCF) antennas are very convenient as they will allow multiple bands of
operation with a simple wire antenna which is fed off center. The Palomar Engineers 4010 OCF
is a very popular antenna and consists of an off center fed dipole with sides of 55 feet and 11
feet and it will work all bands from 40-6 meters. The End Fed OCF uses the same dimensions
but the wire section is 55 feet as in the OCF and the coax outer braid is used for the "other"
part of the OCF dipole. We place a choke on the coax at the 12 foot distance from the
matching unit and we essentially have an OCF antenna with its great frequency range, but
with only a 55 foot wire length instead of the 66 feet required by the regular OCF. You feed the
antenna from one end which may be more convenient for some installations. This antenna
