   Linksys WRT54G series routers fed the antennas with short LMR400 cables, so the effective gain of the complete antenna is estimated at 30 dBi. [ 12 ] This is the largest known range attained with this technology, improving on a previous US record of 201 km (125 mi) achieved last year in U.S.

3. Wi-Fi over Coax - Wikipedia

   en.wikipedia.org/wiki/Wi-Fi_over_Coax

   Wi-Fi over Coax is a technology for extending and distributing Wi-Fi signals via coaxial cables.As an in-building wireless solution, Wi-Fi over Coax can make use of existing or new cabling with native impedance of 50 Ω shared by a Wi-Fi access point, cabling run, and antenna.

   The resulting setup is a low-cost high-quality high-gain antenna. [6] Such setups are widely used in wireless community networks for long-distance Wi-Fi links. Cantennas may be used with other RF devices such as wireless security cameras. [7]

5. Wireless repeater - Wikipedia

   en.wikipedia.org/wiki/Wireless_repeater

   Since only one wireless device can transmit at once, wireless transmissions are doubled (router to the repeater and then repeater to the client versus just router to the client), and so: Wireless throughput is reduced by at least 50%. [1] Wireless interference (e.g., with other networks on the same channel) is at least doubled.

6. Parabolic antenna - Wikipedia

   en.wikipedia.org/wiki/Parabolic_antenna

   The directive qualities of an antenna are measured by a dimensionless parameter called its gain, which is the ratio of the power received by the antenna from a source along its beam axis to the power received by a hypothetical isotropic antenna. The gain of a parabolic antenna is: [3] [12]

7. Antenna types - Wikipedia

   en.wikipedia.org/wiki/Antenna_types

   A directive antenna with moderate gain of about 8 dBi often used at UHF frequencies. Consists of a dipole mounted in front of two reflective metal screens joined at an angle, usually 90°. Used as a rooftop UHF television antenna and for point-to-point data links. Parabolic The most widely used high gain antenna at microwave frequencies and above.
