Description
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/Spinner/Cellflex/RFS are some of the internationally recognised brands and stand for good quality cables.
There are two general types available in this category, smaller diameter H-155 and thicker H-2000. 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 for H2000 or better. If you wish to order greater lengths of cable than displayed below simply order 2 or three of a given length. 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.
