OCF-4010E-3K OCF antenna (Windom)
This is OCF dipole wire antenna also known as Windom antenna fed at 19% from one end. Current type 4:1 (200:50 Ohms) BALUN is another product designed for OCF antennas (Off Center Fed) also known as Windom antenna. Dual cores, total of two (2) 2.4 inch (61mm) wound with PTFE wire is the best CURRENT BALUN design used with unbalanced antennas. It covers 1-54 MHz with almost perfect VSWR terminated into 200 Ohms load, see the VSWR curve at the gallery. Unlike other companies, we do not claim unrealistic power ratings. We are sure it will handle all you have up to a legal limit of 1500W in the USA and even more. It is rated at 3kW ICAS.
BALUN Enclosure is injection molding of PBT20-Polybutylene Terephthalate (PBTthermoplastic polymer) material filled with 20% glass fiber. This UV Resistant/Weatherable polymer offers impact strength, heat resistance (melting point 223 °C or 433 °F) as well it is excellent electrical insulator.
