It would be best to have your antenna placed 30 feet above ground level to give you the clearest over-the-air connection with a tower. For those looking for that height, outdoor antennas are usually a good place to start. You'll want an amplified antenna if you're 30 or more miles away from your local broadcast tower.
Why it's helpful: Placing the antenna near the ceiling generally produces the best results because it puts the antenna above the level of low-lying objects in nearby rooms or outdoors that might block the signal.
A height of 120 feet or even higher will provide even more advantages for long-distance communications. To a distant receiving station, a transmitting antenna at 120 feet will provide the effect of approximately 8 to 10 times more transmitting power than the same antenna at 35 feet.
The higher the antenna is above ground level (AGL), the greater the signal density and the lower the ground loss. Antennas 30 feet or higher capture the full signal. Below 30 feet ground reflections cause multi path interference. The lower the antenna the greater the loss.
As stated earlier, most experts feel that an antenna height of 30 or 40 feet (9 to 12 meters) is optimum for 6 meters.
Your antenna mount needs to be properly grounded for your antenna to function correctly. Without a solid ground, you're bound to get high SWR levels and extremely poor performance.
The height of an antenna has a major impact on its performance. Aspects including the feed impedance, radiation diagram, radiation losses, distance from interference, reduction in possibility of exposure to RF radiation, etc.
Because most of the TV transmitter are horizontal polarized it would be best to start putting the antenna in a horizontal position. One For All antennas receive vertical as well as horizontal signals.
If you want to focus all of the signal to direct it to a distant target, then the high gain antenna is definitely the best choice. High gain antennas need to be pointed in a preferred direction to send RF signal so that limited signal can be intensified in desired location, as illustrated below.
As a rule, it's best to place your antenna where the entire height of the mast can 'see' in all directions – on the roof, or on the roof racks. Use a quality, hinged mount and remember that an antenna works best when installed vertically.
This interference may be caused by equipment in your home, such as hair dryers, sewing machines, electric drills, doorbell transformers, light switches, smartphone chargers, power supplies, computing devices, washing machines, clothes dryers, fluorescent lights, LED lights, or garage door openers.
When you touch an antenna, the capacitance of the touch joint transfers induced RF voltage from your body to receiver already working on noise threshold, resulting in improvement some time. Your body and every other object in path of RF field acts as antenna. More area, more aperture, more gain.
The only legal ground rod must be installed a minimum of 8-foot in the ground.
If both antennas on a mast are connected to remote radios, then a minimum of 2-3 feet of vertical separation is typically OK. If one antenna is connected to an access point radio, then it will be transmitting much more, and thus interfere constantly with the other. In such a case, a lot more separation would be needed.
While a strong signal is often thought of as a plus, a signal that is too high will likely cause pixelation or burn out your TV's tuner. Typically a good signal strength is between 60-65dBuV. You can check the nearest transmitters and signal strength available from your location using the MySwitch website.
Typically, the higher you have your antenna, the better the reception. While signals pass through walls and other surfaces, the more obstructions the signal encounters, the weaker the signal and this causes signal disruption.
This is an indicator of a poor signal. Pixelation can be caused by weather conditions (thunderstorms), interference from nearby appliances or signal interference from other devices.
Luckily, there is little chance of that, because Wi-Fi networks work on different frequencies than digital antennas. Digital TV antennas go up to a frequency of 693.25 MHz, according to Into Tomorrow. Wi-Fi routers, on the other hand, operate on 2.4 GHz or 5 GHz. That's a huge gap between frequencies.
When it comes to choosing the right UHF CB aerial, size is important, but it's probably not what you think. Taller, with higher 'gain' isn't always better. It's a common misconception that a tall CB aerial gives the longest reception and transmission range in all situations.
Prevent Signal Blockage
The 5th wheel will likely be blocking it unless you're using an extremely long antenna. That's when having two antennas comes in handy. With antennas on both sides of your vehicle, you're much less likely to have large dead spots because the antenna system can "see" more.
The dual antenna technology means you always receive the strongest signal automatically whether you're in the high country, on rough terrain or on the flat.
