How much antenna gain do i need




















Some manufacturers label small, indoor antennas with high gain numbers between 30 and 55 dB. This style of antenna is probably paired with an amplifier and the gain value stated on the package is really the gain of the amplifier and not the antenna.

While it is possible to improve reception by using a low-noise amplifier, most of the inexpensive antenna designs actually have low-quality amplifiers and too much gain. Low-quality amplifiers could overload the TV's tuner or set-top receiver, causing signal distortion that can degrade or, most likely, eliminate TV reception entirely. A well-designed, non-amplified unit, also known as a passive antenna, would be the better choice. If television reception requires an amplifier, the best choice is a high-quality, low-noise model, connected as close as possible to the TV antenna.

The reason? Why not share your experiences in the comments below. Great information and since I am a newbie I am reading it all. I am taking my tech exam next month. Sorry I am not buying one from you. I am going to attempt to make 6 or so for family to talk on MURS. I am needing your quick advice on what frequency I am putting into the J pole calculator.

Your j pole for range covers MURS. What freq do I put into the calculator to get my best lengths to build the j pole? You also mentioned in the description, it covers the range. I am confused. I need some help with the calculations for MURS.

I appreciate any help. All coming to you about once a week.
