The four main components of a mast or pole photography system are: (1) the telescoping mast or pole, (2) a high resolution digital camera that is, (3) controlled remotely with a smartphone or computer tablet running a mobile app, and (4) a remote controlled and powered pan/tilt head for pointing the camera.
A mast radiator or mast antenna is a radio tower or mast in which the whole structure is an antenna. Mast antennas are the transmitting antennas typical for long or medium wave broadcasting. Structurally, the only difference is that some mast radiators require the mast base to be insulated from the ground.
Radio masts and towers support antennas (also known as aerials) for telecommunications and broadcasting, including television. Subcategories This category has the following 4 subcategories, out of 4 total.
It is constructed of two telescoping rods attached to a base, which extend out to about 1 m (3.3 feet) length (approximately one-quarter wavelength at 54 MHz) and can be collapsed when not in use. For best reception, the rods should be adjusted to be a little less than 1 / 4 wavelength at the frequency of the television channel being ...
A second problem with electrically short masts is that the capacitive reactance of the mast is high, requiring a large loading coil in the antenna tuner to tune it out and make the mast resonant. The high reactance vs the low resistance give the antenna a high Q factor ; the antenna and coil act as a high Q tuned circuit , reducing the usable ...
(left) Three large fiberglass whips mounted on a mast. (right) Fiberglass whip for 2 m and 70 cm amateur radio bands. The whip antenna is a monopole antenna , and like a vertical dipole has an omnidirectional radiation pattern , radiating equal radio power in all azimuthal directions (perpendicular to the antenna's axis), with the radiated ...

Guyed radio masts are typically tall enough that they require several sets of guy lines, 2 to 4, attached at different heights on the mast, to prevent them from buckling. An exception to multiple guys was the Blaw-Knox tower , widely used during the 1930s, whose distinctive wide diamond ( rhomboidal ) shape gave it the shear strength that it ...
