SE-EF4010: 40 Meters to 10 Meters, 45 ft Low Power End Fed Antenna
Hours: Monday - Friday
9:00 AM to 5:00 PM (CST)
Compact 45 ft multiband End Fed antenna usable from 40 Meters to 10 Meters with the use of a wideband antenna tuner. May be
used on 40 and 20 Meters without the aid of an antenna tuner in some situations (see VSWR plot below). The transformer
is designed with a low power single core 4:1 voltage Unun. This design provides a direct DC ground for effective static
dissipation. The transformer housing is made with American products (except for the UHF connector), consisting of a ABS
plastic housing, plus all stainless steel mounting hardware for years of trouble free service. Ideal for portable or attic
installations where space limitations are a concern. Makes a good companion to stations like the Elecraft K/KX series,
FT-817, IC703, and other QRP radios. Also is a great shortwave receive antenna that can be used from 400 KHz to 108 MHz.
Complete SE-EF4010 assembly. ABS plastic housing and all stainless steel hardware.
Hand Wound low power 4:1 Voltage Unun.

It was a pleasure running into your booth at the Peoria (IL) this past weekend. I purchased one of your
SE-EF4010 antennas, as did my buddy, and with the beautiful day today I thought I'd try it out. I purchased the antenna with
portable operation in mind, so I set up my IC-7000 on a table in the back yard and hoisted the antenna in a tree. Within minutes
I was on the air and made the following contacts, all sideband, with 75 Watts:
DL5ANT in Germany on 15 meters
CE4CT in Chile on
KD8DZ in Ohio on 40 meters
I'm thrilled! The antenna works as well or better than I
