When so loaded the antenna presents a pure resistance to the transmission line, preventing energy from being reflected. The loading coil is often placed at the base of the antenna, between it and the transmission line (base loading), but for more efficient radiation, it is sometimes inserted near the midpoint of the antenna element (center ...
(The term "linear" is not strict: End-sections of a linear antenna far from its center can be bent away from a straight line with only slight or unnoticeable loss in performance.) Dipole Two-armed antennas, like "rabbit ears". For resonance, each arm is slightly under a quarter-wave base to end, which makes the whole antenna nearly a half-wave ...
A short antenna pole next to a house Multiple Yagi TV aerials. Antennas are commonly placed on rooftops and sometimes in attics. Placing an antenna indoors significantly attenuates the level of the available signal. [19] [20] Directional antennas must be pointed at the transmitter they are receiving; in most cases great accuracy is not needed ...
The batwing antenna is a turnstile antenna with its linear elements widened as in a bow-tie antenna, again for the purpose of widening its resonant frequency and thus usable over a larger bandwidth, without re-tuning. When stacked to form an array the radiation is omnidirectional, horizontally polarized, and with increased gain at low ...
LNA-100 Boost Antenna Amplifier. If you’re looking for an antenna amplifier that's easy to set up and minimizes wires in your house, the Winegard LNA-100 Boost is an ideal choice.
The name comes from its resemblance to an inverted letter "L" (Γ). The T-antenna is an omnidirectional antenna, radiating equal radio power in all azimuthal directions, while the inverted-L is a weakly directional antenna, with maximum radio power radiated in the direction of the top load wire, off the end with the feeder attached.
