Best Outdoor Antenna Installation Tips

Antenna Installation Guide - Hints Tips - Electronics Notes

-Looking for more guidance or want to educate yourself before cutting the cord? Here are some tips tailored to safely installing your outdoor TV antenna.
Please note: Every time you move or reconnect your antenna, you must scan for channels on your television. Consult your television owner's manual for more precise guidelines. We include Quick Start guides with all our TV antennas and also provide them here on our website for free.
Installation tips:

1. Before installing an antenna permanently on a roof or in your attic, test reception in that area and other locations prior to installation. To perform a test, connect the coaxial cable from the antenna to your TV. Then, place your antenna in the desired location. Turn on your TV using your TV and, using your remote, complete a channel scan. Once complete, flip through your TV channels and watch for signal interruptions. Make sure your antenna is installed where you get the best signal and the highest number of available channels. Check It Out
2. Higher is always better. Mount the antenna on your roof or in the attic for optimal performance. These locations are more likely to experience fewer obstacles which cause signal interference between the antenna and broadcast towers.

1. Face the front of the antenna toward the broadcast towers. Even multi-directional antennas require this to achieve the best possible reception. Don't know where your towers are? Visit our transmitter locator or download our free Antenna Point app. 
2. Check your outdoor antenna regularly for secure coaxial cable connections and signs of corrosion. Sometimes debris or humidity can interfere with reception. Where possible, cover all connections and use waterproof sealant when installing an antenna mast. (See our included sealing pads for reference.)
3. Installing your antenna near power lines is dangerous. The antenna must be at least 20 ft. (6 meters) away from all power lines. If any part of the antenna or mast assembly comes into contact with a power line, call your local power company. Do not remove it yourself.

Note: Unfortunately, sometimes antennas are returned to us in perfect working order but were returned due to faulty installation techniques. Continue reading for troubleshooting tips.
Troubleshooting tips:
Spotty reception with accessories:

1. For the best reception, make sure the coaxial cable is the correct length for your installation needs. Similar to getting your antenna up high, terminating your coaxial cable at the right length will provide better reception to your television. 
2. If you are using a splitter, diplexer, or your cable run must be longer than 100 ft., consider using a preamplifier to boost weak signals. 

Spotty reception:

1. Reflected signals are also called "multipath interference". For those living close to broadcast towers, signal loss can occur when strong signals bounce off nearby buildings and other surfaces in the area. Aim your antenna in different directions, even sometimes away from the towers, and scan for channels. If this doesn't improve your reception, your installation may require an attenuator.

1. Do not install your antenna near metallic objects or reflective surfaces, as this could also cause signal interference.
2. Since the switch in 2007 from analog to digital signals, receiving TV signal is "all or nothing". You won't see "fuzz" or "snow" on your TV screen if the signal is weak or there is no signal. When a digital signal is received, it will display crystal-clear on your TV. If the signal is interrupted, your TV screen will be blank.

Combining multiple antennas
When combining multiple antennas on the same mast, keep at least 4 to 6 feet of vertical separation between the two antennas to prevent interference. If you want to combine signals from a UHF antenna with a VHF antenna so there is only one down-lead going into your house, use our UHF/VHF signal combiner with a channel filter for each antenna, designed not to pick up out-of-phase signals through the other antenna. For the best results, use equal lengths of coaxial cable from the output of each antenna when connecting to the UHF/VHF combiner.
Optional grounding information
For outdoor TV antenna installations, grounding the coaxial cable will protect your equipment from voltage surges created by nearby lightning strikes but will not protect from a direct strike. Check your local electrical codes to make sure your installation is in compliance. We recommend calling a professional electrician to advise or install your antenna. We have an educational page with suggestions for grounding your antenna.
Safety precautions:
If you are installing an antenna on the roof, assemble the antenna on the ground. Installing an antenna on windy days can be especially dangerous and even slight winds create strong resistance when attempting to set up an antenna or mast. 
Antennas that are improperly installed or mounted on inadequate structures are very susceptible to wind and weather damage. This damage could become life-threatening. The owner and installer assume full responsibility for the installation and verification that it is structurally sound to support all loads (weight, wind, ice, etc.) and is properly sealed against the elements and leaks.

photo transistor circuit

The human eye was a  persistance of vision of about 0.02 second. Therefore a light that flashes on and off more than about 50 Hz appears continuously on. The human ear is much faster and can respond to sound with a frequency Up to about 20.000 Hz. The Light listener transforms the pulsating and flickering of light that eye cannot discern into sounds . The ear can easily hear.

b) Radiant Energy Patents - Various R. E. Circuits and Devices

1. Patent No. 2,813,242, Nov. 1957 L. R. Crump-Atmospheric Energy Device
This radiant energy conversion art is quite significant since it discloses three distinct conversion applications circuits which are both practical and worthy of further study and improvement.
The accompanying schematics show the three versions, along with the identification of each component within the three circuit diagrams. Of particular interest is the circuit diagram shown in FIG. 3, which is the high voltage D. C. conversion, using input coils, tuning capacitor, a transistor oscillator, transformer and diode circuitry. This arrange- ment should offer the best combination of components to produce a high potential output from a radiant energy source.
The circuit version shown in FIG. 2 is for a general low voltage, wattage arrangement which is simple and may be useful for certain applications. The circuit version shown in FIG. 1 is a direct transistor radio operational design, which is self-explanatory.
There is a general similarity of Cramp's work to that of Lester Hendershot, except for the addition of the antenna and diodes in Crump's art. It should be noted that the tuning capacitor in Crump's circuit is a desirable feature in any Radiant Energy device, since these circuits need to be "tuned" to R.E. frequency. Hendershot's permanent magnet/& clapper component is a desirable dynamic feature which might be used to advantage within the Crump circuitry, but this will require some experimentation before an optimum match is obtained.
The addition of the diodes in Cramp's circuitry increases polarization efficiency, and generally improves the R. E. conversion value of this device. It should be noted that it is believed that Dr. T. H. Moray also used antenna-coupled coils directly connected to his 100 foot long directional antenna, as the Crump input circuitry indicates.
In a general manner, the Cramp circuitry appears to bridge between the art of Moray and Hendershot in the selec- tion and application of the various components, as can be seen from a review of their circuit components.

2. Xtec Corporation, of New Britain, Conn, with reference to Crump's Patent above, (Pats, pending)
This group has developed an antenna/amplifier arrangement which is said to collect and amplify atmospheric/ra- diant energy. The antenna operates as a dependent power supply for the system. An input signal turns on the power amplifying antenna which draws on the potential between two points in the environment to complete a circuit through a form of inductive coupling. The result is amplified energy for the load to be driven.
