Unlike many END FED antennas on the market, this one does not require the Antenna Tuner to operate.&nbsp; &nbsp;Due to the High Impedance feed point, the antenna is less height-dependent. You can put it up at 10 or 50 feet in the air without much change in VSWR values.<\/p>\n<blockquote><p><strong>*This is perfect antenna for ALE HF-link&nbsp; stations, NVIS, MARS, ARES, EMCOMM etc.<\/strong><\/p><\/blockquote>\n<p>Various installations such as horizontal, vertical, inverted V, inverted L, etc. are possible.&nbsp; Your VSWR values could vary with different wire configurations and the height of installation.<\/p>\n<ul>\n<li><strong>NO TUNER needed!<\/strong><\/li>\n<li><strong>NO counterpoise is needed!
