The most common types of indoor antennas are the dipole [2] ("rabbit ears"), which work best for VHF channels, and loop antennas, which work best for UHF. [3] Outdoor antennas on the other hand are designed to be mounted on a mast on top of the owner's house, [ 4 ] or in a loft or attic where the dry conditions and increased elevation are ...
8-Port TV Distribution Amplifier. For households with multiple TVs, the Antennas Direct 8-Port TV Distribution Amplifier can split a signal with no noticeable impact on signal quality.
Belden 1829AC Coax - Series 6 has a loss of 4 db/100 feet at 500 MHz (TV Channel 18)- 495.250; Channel 32 which is 580 MHz, Channel 52 is 700 MHz a 5 db loss At TV channel 2, the cable would have a loss of 1.4 db. So at channel 18 you would lose more than 1/2 the power in 100' of cable between the antenna and the TV.

The VHF band is further divided into two frequency ranges: VHF low band between 54 and 88 MHz, containing channels 2 through 6, and VHF high band between 174 and 216 MHz, containing channels 7 through 13. The wide spacing between these frequency bands is responsible for the complicated design of rooftop TV antennas.
A Tower Mounted Amplifier (TMA), or Mast Head Amplifier (MHA), is a low-noise amplifier (LNA) mounted as close as practical to the antenna in mobile masts or base transceiver stations. A TMA reduces the base transceiver station noise figure (NF) and therefore improves its overall sensitivity ; in other words the mobile mast is able to receive ...
A batwing or super turnstile antenna is a broadcasting antenna used at VHF and UHF frequencies, named for its distinctive shape resembling a bat wing or bow tie. Stacked arrays of batwing antennas are used as television broadcasting antennas due to their omnidirectional characteristics. [1] Batwing antennas generate a horizontally polarized signal.
