Indoor building antennas fall into three categories, panel, dome and desktop. Panel antennas are the most powerful and can be mounted in a variety of ways. Dome antennas provide for wider coverage areas and are designed to be mounted onto a celling. Desktop antennas are placed on the corner of a desk and offer a localized coverage throughout the desktop area.
Panel antennas are the most powerful and versatile option. It is wide-band giving it the ability to work for many cellular bands with a maximum gain of 10.6dB on the 1900MHz band and average gain of 7.7dB on all North American bands. It can be mounted in a variety of ways including the ability to mount it onto a wall, onto a ceiling, window and outdoor pole. It is available in 50 ohms and 75 ohms varieties. It is directional meaning it transmits the signal in one direction so it is required to be pointed in the area where the boosted signal needs to be transmitted. This antenna is available with a wall mount (50 ohm 301135 and 75 ohm 301155), with a ceiling mount (50 ohm 304451 and 75 ohm 304471), with a window mount that utilizes suction cups (50 ohm 304452 and 75 ohm 304472) and with a pole mount (50 ohm 304453 and 75 ohm 304473). The panel antennas which include the pole mount are slightly different in the sense that they are weather resistant as they are designed for outdoor use. The mounts are available separately along with other mounting options. These include the wall mount (901143), the ceiling mount (901140), the window mount (901141) and the pole mount (901142). Other options include an in-wall mount (901123) and corner wall mount (901135).
Dome antennas are designed to be mounted onto a ceiling and provide for a wider coverage area. This type of antenna is available in three varieties, two of which are dual-band (North American bands 1900Mhz and 800MHz) with the other being single-band (for the 800MHz band). The differences between the two dual-band inside antennas are the impedance and connectors. These antennas are both directional meaning they only transmit the boosted cellular signal on the direction where it is pointed with maximum gain of 4.1dB on the 1900MHz band. The other dome antenna is designed to transmit signal from the 800MHz frequency and should be considered mostly for iDEN solutions. It offers a maximum gain of 5.4dB on the 800MHz band. This antenna is dual-directional. It can transmit boosted signal to areas in front of it as well as behind it allowing for it to be mounted either onto a ceiling or onto a wall. Dual-band panel antennas include the 301121 a 50 ohm with N-Female connector (301121) and a 75 ohm with F-Female connector (301151). Single-band panel antennas include one which is 50 ohm with N-Female connector (301123). There is one mount which works with all dome antennas (901125) which is a bracket that any of these antennas can easily mount into.
Desktop inside antennas are the last type of inside antennas. It is required to be placed onto the corner of a desk and transmit the boosted cellular signal to the area within the desk. It offers an attractive low-profile look and does not require the purchase of any mount. It is available in three varieties with the only difference being the connector. It offers a maximum gain of 3.4dB on the 1900MHz. They include a 5-ft RG174 cable. Options include the desktop antenna with an FME-Female connector (301208), with a TNC-Male connector (301209) and with an SMA-Male connector (301210).
