The first English-language release of "Antenna House XSL Formatter" was announced on the XSL-List mailing list on 22 November 2000. [2]Antenna House XSL Formatter V1.2 Alpha was one of six XSL Formatters that provided the test results [13] for the test suite for the XSL 1.0 Candidate Recommendation that was required for XSL 1.0 to proceed to the Proposed Recommendation stage.
The antenna pattern is the response of the antenna to a plane wave incident from a given direction or the relative power density of the wave transmitted by the antenna in a given direction. For a reciprocal antenna, these two patterns are identical. A multitude of antenna pattern measurement techniques have been developed.
William Ittner Orr (1919–2001) was an engineer, educator, communicator, and ham radio operator. [1] [2] [3] He was the American author of numerous amateur radio and radio engineering texts.
An antenna's impedance is different at different frequencies. An antenna tuner matches a radio with a fixed impedance (typically 50 Ohms for modern transceivers) to the combination of the feedline and the antenna; useful when the impedance seen at the input end of the feedline is unknown, complex, or otherwise different from the transceiver.

Louis Varney (G5RV) invented this antenna in 1946. [4] It is very popular in the United States. [5] The antenna can be erected as horizontal dipole, as sloper, or an inverted-V antenna. With a transmatch, (antenna tuner) it can operate on all HF amateur radio bands (3.5–30 MHz). [5] [6]
