The antenna well proved itself in operation. With the output of 100 W on 80 m band Europe reports at 59 in the evening; in the daytime within the radius of 200 km the communication is in VHF. Also, a decreased noise level of that antenna was noted in the reception mode, probably due to a short-circuited matching transformer.
No external antenna tuner is required as long as the antenna VSWR is 3:1 or lower. The amplifier will perform the functions of an antenna tuner, enabling you to change antennas faster and use them over wide frequency ranges.
The 80-10-JR-KW consists of the two components shown in Figure 1 – the antenna wire and an impedance transformer. Designed to be used on 80, 40, 20, 15, and 10 meters, the EFHW antenna wire is approximately one half-wavelength long on 40 meters with a coil and extension that add 80 meter operation.
Antenna for 80 – 10 Meters Bottom Line The EFHW-8010-1K provides an easy-to-deploy antenna that can be operated on all HF bands, except 60 meters, with a low enough SWR to be used without an antenna tuner on most bands. Being able to feed the antenna from an end may make it a good solution for many support configurations. Figure 2 — The
Rated for full 1500 watts PEP and 450 watts CW (ICAS). 1.8Mhz – 31 MHz. 5KW model is 5KW PEP, 1500 watts CW/RTTY/FT8. Typical size id 1005/F(MHz) and cut for lowest frequency in band segment. For best results support antenna at least 30+ feet – the higher the better radiation.
The DX Engineering MBVE-2 is a fast taper 33 feet high multi-band vertical antenna system. The vertical antenna operates from 80 meters through 10 meters using a good quality outboard customer supplied tuner. There are no traps, coils or linear loading elements to rob power.
OCF antennas are very convenient as they will allow multiple bands of operation with a simple wire antenna which is fed off center.
