   The Antop amplifier features a gain of 16 decibels and a short- and long-range reception switch, allowing you to control how much extra gain it pumps into the signal. ... WA-2608 Amplified Outdoor ...

3. Long-range Wi-Fi - Wikipedia

   en.wikipedia.org/wiki/Long-range_Wi-Fi

   A typical wireless router in an indoor point-to-multipoint arrangement using 802.11n and a stock antenna might have a range of 50 metres (160 ft) or less. Outdoor point-to-point arrangements, through use of directional antennas, can be extended with many kilometers between stations.

4. Radio masts and towers - Wikipedia

   en.wikipedia.org/wiki/Radio_masts_and_towers

   For transmissions in the shortwave range, there is little to be gained by raising the antenna more than a half to three quarters of a wavelength above ground level, and at lower frequencies and longer wavelengths, the height becomes infeasibly great (greater than 85 metres (279 ft)). Shortwave transmitters rarely use masts taller than about 100 ...

5. Antenna measurement - Wikipedia

   en.wikipedia.org/wiki/Antenna_measurement

   The first technique developed was the far-field range, where the antenna under test (AUT) is placed in the far-field of a range antenna. Due to the size required to create a far-field range for large antennas, near-field techniques were developed, which allow the measurement of the field on a distance close to the antenna (typically 3 to 10 ...

6. Log-periodic antenna - Wikipedia

   en.wikipedia.org/wiki/Log-periodic_antenna

   Being log-periodic, the antenna's main characteristics (radiation pattern, gain, driving point impedance) are almost constant over its entire frequency range, with the match to a 300 Ω feed line achieving a standing wave ratio of better than 2:1 over that range.
