Antenna installation offers a spectrum of choices depending on the selected location and the specific type of antenna. Below is a detailed examination of various antenna mounting methods.
Indoor Antenna Installation
Indoor antennas represent the simplest installation category. Options range from basic rabbit ear antennas, with or without amplifiers, to small directional antennas, and flat panel designs. These can be easily positioned near the TV, oriented towards the transmission source.
Attic Mounts
Attic mounts are viable in areas with strong signal reception. While often straightforward and economical, several factors can limit attic installations, such as limited space, structural impediments, or materials that hinder signal reception like metal in walls or insulation. The use of a roof-type mounting bracket can be adapted for attic use, attaching to rafters and supporting the antenna on a short mast. It’s crucial that the antenna doesn’t make contact with the attic floor and that it is correctly oriented.
Antennas in attics can either be small directional or omnidirectional. Directional antennas must be aligned towards the desired TV stations, while omnidirectional antennas capture signals from all directions, potentially leading to more interference.
Chimney Mounts
Chimney mounts, though common, may not always be the best choice. The proximity to smoke and gases can deteriorate the antenna’s lifespan and performance. These mounts are suitable only for stable, vertical chimneys. Over 10 feet of un-guyed mast on a chimney can be risky in windy conditions. Chimney mounts should keep the antenna clear of most smoke and gases but should not extend more than 10 feet above the chimney without proper guying.
Roof Mounts
Roof mounts come in two primary types: base mounts and tripods. Tripods, being more stable and rigid, are preferable, though more costly. Base mounts can be effective when cost or space is a concern, but require proper guying. For additional stability, combining with a tripod is recommended.
Wall Mounts
Various wall mount brackets are available. For strength, the brackets should be spaced as far apart as practical. Masts extending more than 10 feet above the top bracket should be guyed for safety.
Ground-Level Mounting
When roof mounting isn’t feasible, ground-level mounting is an excellent alternative. This method, involving a firm base and possibly multiple wall mount brackets, provides a robust setup. Using telescoping masts can offer additional height and stability without the need for guy wires.
Telescoping Masts
Telescoping masts are ideal when standard mast lengths are insufficient. These masts offer greater strength and rigidity and can extend up to 15 feet above the roof line without requiring guy wires. They are best used with ground or roof mounts but not recommended for chimney or wall mounts due to their weight. Freestanding telescoping masts should be guyed every 10 feet, and those mounted near a building should be supported near the roof line, then guyed appropriately above it.
