2. List of tallest structures in the United States - Wikipedia

   en.wikipedia.org/wiki/List_of_tallest_structures...

   The tower is home to WIMZ-FM 103.5, whose antenna is at the top. The tower is located 1 mi (1.6 km) east of House Mountain and stands 1,752 ft (534 m) above ground level. When used for television broadcasts by its former owner, Multimedia, Inc. (former licensee of WBIR-TV , Knoxville) it was shielded by mountains from the audience in the ...

3. Radio masts and towers - Wikipedia

   en.wikipedia.org/wiki/Radio_masts_and_towers

   One problem with radio masts is the danger of wind-induced oscillations. This is particularly a concern with steel tube construction. One can reduce this by building cylindrical shock-mounts into the construction. One finds such shock-mounts, which look like cylinders thicker than the mast, for example, at the radio masts of DHO38 in Saterland.

5. Monopole antenna - Wikipedia

   en.wikipedia.org/wiki/Monopole_antenna

   The horizontal gain continues to increase up to a maximum of about 6.6 dBi at a length of five-eighths wavelength ⁠ 5 / 8 ⁠ λ so this is a popular length for ground wave antennas and terrestrial communication antennas, for frequencies where a larger antenna size is feasible. The input impedance drops to about 40 Ohms at that length.

6. Mast radiator - Wikipedia

   en.wikipedia.org/wiki/Mast_radiator

   Usually a chain-link fence is used, but sometimes wooden fences are used to prevent currents induced in a metallic fence from distorting the radiation pattern of the antenna. An alternate design is to mount the mast on top of the antenna tuning hut, out of the reach of the public, eliminating the need for a fence.

7. Antenna types - Wikipedia

   en.wikipedia.org/wiki/Antenna_types

   The category of simple antennas consists of dipoles, monopoles, and loop antennas. Nearly all can be made with a single segment of wire (ignoring the break made in the wire for the feedline connection). [citation needed] Dipoles and monopoles called linear antennas (or straight wire antennas) since their radiating parts lie along a single ...
