It is recommended that you use the coaxial cable included with the antenna. Using too much coaxial cable can result in as much as a 1/3 of the signal being lost. Our antennas include 10 to 12 feet of coaxial cable. As a general rule, we recommend adding no more than 25 feet of additional coaxial cable with the antenna. You can use an coaxial cable coupler to combine two coaxial cables.
Less is more with coaxial cables for indoor antennas. Also do not coil the coaxial cable as this can cause signal loss too. Instead let the cord lay uncoiled if possible. Again...less is more!
Please remember that the additional coaxial cable needs to be AFTER the amplifier, between the amplifier and the TV for best performance!
*Please note: in some locations where the signal strength is strong, a longer run of coaxial cable may work perfectly for you. This depends on several factors in your antenna set up. Test your antenna with a longer run of coaxial cable first to see your location supports additional coaxial use. Historically the less coaxial cable you can use the better the reception chances but not all areas are the same.
*Please note: in some locations an indoor antenna may be able to support using a splitter to split signals to multiple TVs. We suggest you test this with your indoor antenna to see if it will work in your area. Each time a signal is split to another TV the signal becomes weakened by 1/2. Historically, smaller indoor antennas are not able to send signals to more than one TV. It really depends on the signal strength from the broadcast tower. Contact us for more information.
