Coaxial cable of various types Your transmission system is only as strong as its weakest link. Using cheap or inferior cable can severely limit your broadcast power and range. The best way to determine if a cable is right for your application is to make sure that it has a low dB loss at your frequency. Belden is an internationally recognized brand and stands for good quality cables. Cables are available with professional connectors installed, please specify type at ordering!
There are two types available, smaller diameter H-155 and semi-rigid thicker H-500. For short runs (~ 5 meters) it doesn't make sense to invest into expensive cable, but as your cable length approaches 10-20m or even more, it becomes a real problem and it is worth spending a little extra. If you wish to order greater length of cable than displayed below, simply order 2 or three of a given lenght. For example, if you order 2x20m of Belden H-155, we won't cut the cable but rather send you a full length of 40m. Technical specifications for RG178/U TEFLON brown:
- Diameter 2 mm, our tiniest cable
- dB loss/100m @ 100MHz ~25dB
- Suitable for very short runs (1m-2m) and not more than 100W power
- Very suitable for internal interconnection due to heat resistance, virtually impossible to burn isolation while soldering, also suitable for wilkinson combiners and wideband transformers. Technical specifications for RG174:
