![]() NOTE: grounding does not affect antenna tuning. *Grounding at the transformer box or end of the coaxial cable is recommended for the protection of your equipment from an electrostatic buildup in order to prevent ESD- electrostatic discharge. 250W continuous in digital modes such as FT8 etc.Grounding of cable at the entrance to the home is recommended.For Pole or tower installations additional installation hardware is available on our “Accessories” page. Measured VSWR in the gallery are taken with the antenna in an inverted V shape with the center of wire at 20 feet and ends a few feet above the ground, your values could vary with the way and height of installation. Various installations such as horizontal, vertical, inverted V, inverted L, etc. *This is perfect antenna for ALE HF-link stations, NVIS, MARS, ARES, EMCOMM etc. This is the smaller version of our EFHW-8010-2K-Plus model, see the comparison image. The average loss of less than 0.4dB is unmatched by any other similar transformer on the market proving our worldwide leadership in the design of high ratio-wide bandwidth RF transformers for 3-30MHz. The antenna transformer is optimized for the lowest insertion loss 3.5-30MHz featuring three stacked cores and a transformation ratio of ~56:1 (~2800:50 Ohms). It is a resonant Half wave on 80m (3.5MHz) therefore also resonant on second, third, and fourth harmonics, etc. Unlike many END FED antennas on the market, this one does not require the Antenna Tuner to operate.
