Can I extend the range of my automatic garage door opener?
Any antenna works best by mounting vertical to the ground. Garage door openers are designed for the antenna to be mounted inside the garage, and on the opener so the only way for them to mount vertically is below the unit, toward the floor. There is no reason that these antennas could not be mounted up toward the roof, but they just aren’t manufactured that way. Additionally, transmitter antennas must be specifically designed for the frequency on which they operate. A receiver antenna can be of any length, but again, the considerations for extending one from the receiver require the ability of a communications technician to make it work. This is due to the fact that any place an antenna touches, anything it is behind, any interference of the ability for it to ‘see’ a signal only serves to reduce the efficiency. You can extend the reception range of the receiver you have, but you must properly use a coaxial cable of the proper impedance to extend the antenna. When you do this your best
