FAQ:
Which Antenna should I use? High Gain antennas are very directional toward the horizon. Our CA40M antenna is are great for flat terrains and when the towers are more than 10 miles away. The CA24M antenna works well with in countryside interstate highway travel allowing for modest gain and medium range towers. Our CA4M, CA10M and CA12M antennas are great in most circumstances. They work well within cities and mountainous terrains. They are less directional with a wide range of coverage. They work well with any of our boosters. Do I need to mount the antenna on a metal surface for it to work? The magnetic mount is only there to hold the antenna in place. There is no metal contact between the antenna and the surface. However, the proximity of the metal adds to greater distance .
What Does Gain Have to do with anything? Gain is the measurement of how well an antenna compares to a simple antenna form know as a dipole. It is measured in dB. For every 3 dB the performance of the antenna doubles. 3 dB is 2 times. 6 dB is 2x2 = 4 times. 9dB is 2 x 2 x 2 =8 times. 10 dB is exactly 10 times. The antenna itself does not really add any energy or increase the signal strength of the cell phone, but rather better utilizes what is already there. But you shouldn't base your decision on choice of antenna on gain alone. That is because the higher the gain, the more directional the antenna becomes towards the horizontal. See WHICH ANTENNA SHOULD I USE for more information. What is Effective Gain ( dBe)? Effective Gain is the expected performance of the external antenna when compared to the antenna that comes with the cell phone. A cell phone internal antenna has -7 dB of gain. That's right. It actually looses signal strength. Adding and external antenna, you make up the loss of 7 dB and add the gain of the external antenna. That means that our CA04M 3 dB gain antenna has an effective gain of 7+3 = 10 dB effective. Our competitors like to try to show this value as the actual gain of the antenna to make you think that there antenna is better than ours. Don't believe them! They are really looking at effective gain which is not an industry standard. . |
