Coaxial Cable Assembly Loss
Attenuation or loss is a key specification for all coax cables. The function of a coax cable is to transfer radio frequency power from one point to another, however, some power is lost along the length of the RF cable and through the connectors due to noise, cable imperfections, resistance and other factors. The power loss caused by a coax cable is referred to as attenuation and is defined in terms of decibels per foot at a given frequency.
The key elements which affect cable signal loss are:
- length of the cable
- shielding (diameter) of the cable
- number of connectors
- quality of the cable assembly components
For short distances (10 feet or less), the signal attenuation at 3G/4G/LTE frequencies is negligible for most applications, so LMR100 or LMR195 sized coax is appropriate. At longer distances, thicker coax cables are required to minimize signal loss. To prevent excessive signal loss, shorter cables should NOT be linked together to make a longer cable. It is best to use a single cable whenever possible. It is also acceptable to use a thick cable for the long portion of a cable run and a short thin cable to connect to equipment or antennas, but always try to minimize the total cable length and number of connectors.
Proxicast's coax extension cable assemblies are constructed with top quality extremely low-loss cable and gold plated connectors. Each cable assembly is fully tested when manufactured. Proxicast recommends LMR195 coax for assemblies up to 10 ft, LMR240 for lengths up to 25 ft and LMR400 for lengths up to 50 ft. Custom cable assemblies are also available by contacting Proxicast with your application requirements.

SMA Female jacks are now the most common RF connector used on 3G/4G/LTE cellular modems, routers and signal amplifiers; some devices may also use N, FME, SMB or other connectors - check with your equipment manufacturer.
Many indoor cellular antennas have SMA Male plug connectors; most outdoor antennas have either N-Male or N-Female connectors.
RP-SMA (Reverse Polarity) connectors are commonly used on Wi-Fi equipment, including devices that combine cellular and Wi-Fi radios. SMA and RP-SMA connectors will not mate.
Video equipment (cable TV, satellite TV, closed-circuit TV, etc) often uses "F" connectors - these are similar to SMA connectors in size and appearance but they will not mate with SMA connectors. Also, most video systems require 75 ohm coax cable rather than the 50 ohm cable used for RF.
Please see the photo gallery above for close-up pictures of the exact connectors on this coax extension cable and carefully note the gender of the connectors that you need to ensure male-to-female mating.
Note: All outdoor coax connections should be weather-proofed to minimize damage caused by moisture in the connectors or cabling. Use our Self-Bonding silicone tape (ANT-900-002) for fast and easy connection sealing.
