Description
OCF-4010E-3K OCF antenna (Windom)
The 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, a 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 some competitors, we do not make unrealistic power rating claims. Our OCF Windom 3k will handle power ratings up to the legal limit of 1500W in the USA and elsewhere beyond. It is rated at 3kW ICAS.
BALUN Enclosure is an 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 an excellent electrical insulator.

I have been using this antenna for a couple of months and can confirm the other reviews.
It is made with very good quality material, it is easy to install and so far the performance in both 20 and 40m bands is great.
I have been using it with an ICOM7410 on digital modes and have worked hundreds of stations around the world.

This antenna does exactly what is claimed.
Very low SWR on all advertised bands without a tuner.
VERY well made.

Antenna performance is awesome. Center hung from tree at 35 feet. Ends lower forming inverted V. Noise floor so low it’s not moving S meter on FTdx10. Worked Croatia on first day. This is a great antenna.

This is an excellent antenna. I have the feedpoint up aboout 37 feet and the ends up about 12 feet. Working DX into Italy, Slovenia, Vancouver, Mexico from Durham, NC with 5 x 9 reports. All 4 bands have low SWR. Best dipole I have ever owned.

Well constructed and works on 40-20-15-10-6 without a tuner.
Also will work on 17 and 12 with my rigs built in tuner.
I get good signal reports from all over the world with only 100 watts. I can also throw in heavy attenuation and clearly hear every word a station is saying even with no movement on my S-Meter.

Antenna has been working great! Has survived the many storms that we have here in NC!

Still working today it’s amazing

I own several MyAntennas End feed antenna products. I and satisfied that they are the best.
Daniel –
Outstanding antenna, true to advertised SWR, well built. Have two more End Fed My Antennas as well with the same results.
Al Sutton –
Great product I also have several End Feds from My Antennas and they are absolutely the best. My wish would be a Myantennas endfed for SOTA operations.
