Call 0345 2300 599The Momobeam MOMO-EF1040-1KW is a standard End Fed wire antenna designed for multi-band HF operation on 40m, 20m, 15m and 10m. It is a strong choice for operators who want a simple, efficient wire antenna for fixed station use, portable operation or general HF activity without the complexity of a multi-element antenna system.
This 1kW version is suitable for higher power HF installations and is ideal for operators who want a robust multi-band antenna for regular use. It can be installed horizontally, as an inverted L or as a sloper, giving flexibility depending on your available space, supports and operating location.
As an End Fed antenna, the MOMO-EF1040-1KW is fed from one end of the wire, making it especially useful where a centre-fed dipole would be difficult to install. It uses a long half-wave radiator with a 49 to 1 wide-band impedance transformer, designed to transform the high feed point impedance closer to 50 ohms for multi-band operation.
The antenna is built using coated copper core wire, UV-resistant box and wire materials, and stainless steel hardware for reliable outdoor durability. When installed as high as practical, ideally no less than 10 metres, and kept clear of nearby obstacles, it can provide a typical match of better than 2 to 1 on the supported bands. In some installations, minor trimming or the use of an internal or external tuner may help optimise SWR.

Installation Notes
For best performance, install the antenna as high as practical, ideally no less than 10 metres, and keep it clear of surrounding objects. SWR and tuning will vary depending on height, layout, nearby buildings, trees and ground conditions. A radio’s internal tuner or a suitable external tuner may help fine-tune the match where required.
S.W.R.(*) By correctly installing the antenna at a height of no less than 10 meters and free of obstacles, we will achieve excellent impedance matching on all bands (better than 2:1). In some situations, it may be necessary to adjust the impedance to improve SWR. (Your radio’s internal tuner or an external tuner will help.
