Product Description

DIPLEXER SC-DPLX-01 by SureCall.

With the SureCall DPLX-01 you have a diplexer capable of splitting low or high level signals. In the process, it will isolate the most ideal frequency transmission. The wide band SC-DPLX-01 makes sure the signal of a carrier is received. It does not really matter whether the signal is the weakest or not. The diplexer brings together two antennas to a single port. 

Low and high cell phone frequencies falling within the 698 and 787 MHz-824 and 2200 MHz range are split with ease. Courtesy of a wideband type of design, it is able to accommodate lots of combined solutions from the AWS band (2100MHz), PCS (1900 MHz), Cellular (800 MHz) and LTE (700 MHz). Isolation is of the highest level between the ports at the same time ensuring insertion loss remains the lowest possible on any of the paths. With an Impedance of 50 Ohm, the LTE ready diplexer has a higher rejection level to help prevent any interference in a compact design. Alternate part numbers are: CM-DPLX-01/ CMDPLX-01/ CMDPLX01/ CMD-DPLX01. UPC: 896831002265.

Wide-band diplexer provides easy, reliable splitting of cellular bands including LTE 700 MHz, Cellular 800 MHz, PCS 1900 MHz and AWS 2100 MHz. This design allows for excellent isolation between outputs while maintaining low insertion loss, with systems designed for 50 ohms impedance. The compact design protects the unit from interference, and allows it to be carried easily and installed without a hassle. A temperature rating between -40o and 185o F means this cost-effective solution can function reliably over time in a wide range of environments. This diplexer provides an excellent option for a variety of cell frequencies and needs.

Questions & Answers


Ask a Question
  • Can this be used to combine and split a signal from an OTA antenna and cable internet signal? I read I'd need 2 diplexers to do this but might depend on the right one.

    It splits the lower LTE 700 MHz frequencies from the higher Cellular 800 MHz on up.

Note: For any signal booster to help, outside signal strength must be at least -110 dB or there must be a clear line of sight to a cell tower that is within twenty miles. Before ordering, please check outside signal level in decibels or ensure that you can make and hold a phone call at any good spot outside where you can mount an exterior antenna. Square footage stated in signal booster listings is based on good signal outside. If it is any weaker, the boosted sq. ft. area will be considerably lower, accordingly.

Kevin K. of Anderson, California gave the following review:

Website is easy to use with plain straight forward info but could have had more on testing signal strength to make sure you get a strong enough booster.

Therefore, please note that stated sq. ft. coverage is based on good signal outside. For best results: If outside signal is weak, we suggest choosing the next higher sq. ft. coverage kit. If outside signal is very weak, we suggest choosing the kit with even more higher sq. ft. range bracket. Basically, higher the sq. ft. bracket, the more powerful the signal amplifier with greater Gain as well as higher uplink and downlink output power.

If outside signal is too weak (weaker than -110 dB), submit request for cell coverage solution assessment. Upon receipt of questionnaire, we will perform residential or business site survey. This will help us determine the system that is needed to improve cell coverage. Then, we will create system design using that system such as femtocell, active or hybrid distributed antenna system (DAS), or other carrier feed signal enhancing method available that will work at your signal-challenged location. Finally, we will schedule for installation after equipment and installation service quote has been approved by you, or your company.

For non installation-included kits: Most home / office / building cell signal booster kits only include bracket to mount exterior antenna on outside wall, edge of roof, or existing pipe up to 2 inches in diameter. Mounting pole not included with most kits, unless stated specifically that it is included for free. Therefore, a mounting post must be purchased separately if you will require it to mount exterior antenna.
