Product Description

With SureCall N-Male to F-Female Connector/ Adapter (SureCall SC-CN-20 or SC-CM-20), you can convert your SureCall booster kit to allow for easy installation to pre-existing wire structure. Easily combine two coaxial cables with SureCall Type N-Male to Type F-Female Adapter Connector. This barrel connector allows SureCall’s 50 ohm boosters to retro into any building with existing 75 ohm (RG6/ RG11) cable.

Sure-Call F-Female to N-Male adapter SC-CN-20 comes in handy in the conversion of connectors of diverse size ends to amplifiers, antennas and cables. It is a stainless steel connector. It is weather resistant. This cable connector is designed to meet international standards. It is a great way to change or extend the gender and connector type. Alternate part numbers are: Sure Call SCCN20/ SC-CN20/ SCCN-20 or SCCM20/ SC-CM20/ SCCM-20 and Cellphone-Mate CM-CN-20/ CMCN20/ CM-CN20/ CMCN-20. UPC: 857593005826.

Questions & Answers


Ask a Question
  • This connector makes the connection from 50 Ohm to 75 Ohm, but does not convert 50 to 75 Ohms? A balun would be required. Can you supply the conversion? Please forward this to you engineering department.

    The impedance mismatch only creates an SWR issue where it increases SWR by 0.5 so where it was 1.3:1 it would be 1.8:1. While doing tests on Wifi panels a few years ago at 2.4GHz with a cheap connector adapter, we lost 1.2 dB in test chamber testing. This was on a 14 dBi panel. The insertion loss of said plain adapter is only 0.2 to 0.35 dB depending on the frequency. If you look at this workbench grade transformer (it is not a BALUN) the band width is limited to 2.3GHz. It is difficult to make a very wide band Transformer. Using other in-line transformers, usually  N male N female also have the issue of a thinner pin diameter for the 75 Ohm connector. Then it would have a improper mating issue with the 50 Ohm N female on the antenna. The best solution is to run a 50 Phm cable to the device. If the device is 75 Ohms, exchange it for a proper 50 Ohms device as all transceivers are 50 Ohms. Thank you.

  • Is this an adapter to connect a rg11 female to an rg 6 male

    No, sounds like you need F-Male to F-Female connector.

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.
