OCF-3K80 Multi-Band Dipole
The OCF-380 is designed for low to medium power levels. It will work well on the 80, 40 ,20, 17,12, and 10 meter
ham bands with no need for tuning.
The antenna can be mounted as a dipole or inverted vee. It is complete, cut, tuned, and ready to
The OCF-3K80 is complete with a 4 to 1 Balun. It can be fed with standard 50 ohm coax . It is 133 feet long. 45 feet
on one Leg and 88 feet on the other.
The antenna wire is composed of 2 conductors with 7 strands per side.
4 strands are copper and
3 strands are steel. The wire is rated at 200 lbs tensile strength.
This wire will not kink and is very easy to handle.
The Center insulator
is made of quality schedule 40 PVC and Quality zinc plate eyebolts
For the size, weight and cost, I simply do not think there is a
better performing antenna when the user is limited to a single or wire type antenna. Multi-band, high performance and high power handling, with
utmost simplicity and ease of use. You will not be disappointed.
