Coax stripper

When do you need a coax stripper?

A coaxial cable provides transportation of image and sound, particularly TV and radio signals. For this purpose, these cables are laid to the central receiving point within a building and from there to the various contact points connected to it. Coax cables are also often (still) laid between the contact points and the various playback devices, although HDMI cables or even wireless connections are now also used for this purpose. Coax cables going to and from the connection points in a building are often supplied by the meter and without fixed connectors. Thus, these must always be stripped with a coax stripper in order to correctly fit them with connectors. The cabling towards equipment, on the other hand, is usually sold at the correct length including pre-assembled connectors. These also sometimes need to be shortened and you can do that with a coax stripper.

Construction of coaxial cable

.

Why is a coaxial cable constructed so complexly? That has to do with the fact that the signal to be transported must remain as interference-free as possible, otherwise the image and audio signal will suffer badly. A lot of effort has therefore gone into shielding the cable. To begin with, a coaxial cable has a solid copper core. Around this is a core jacket, an insulator. This insulator, in turn, is often wrapped by an aluminum shielding foil that is also bonded. Around the foil is another jacket, usually made of copper, and around this is the outer jacket. So there are three jackets around the core, and in principle only the outer jacket needs to be stripped. The other 2 jackets usually need to be adjusted to length. The role of a good, adjustable coax stripper in this type of precarious job is therefore obvious.

Cable diameter and choice of coax stripper

Although the construction of this type of cabling is basically always the same, there are quite a few different coax strippers for sale. This has to do with the fact that coaxial cables come in quite a few different thicknesses. Although a thick cable physically offers the best shielding and the least attenuation, it is not always convenient. They don't fit everywhere, are sometimes not flexible, nor do all connectors fit this type of cable. Either way, the smartest thing to do is when you buy a coax stripper that fits the thickness of your coax cable used. Common is an outer diameter of 7mm, but we have models in our range that are suitable for diameters from say 3mm up to 28mm.

Coax stripper with multiple blades

.

Although in principle a coax stripper always strips the outer jacket, the shielding of the copper core and the inner jacket will also have to be cut to size in order to be attached to the connectors. This can be done manually or with extra help. It just depends on what your preferred method of working is. We have in our range of coax strippers versions with 1, 2, 3 or even 4 blades. With a coax stripper with 2 blades, you fit both the inner jacket and the copper core shield in one operation. With a coax stripper with 3 blades you strip all three jackets in one operation, while with a coax stripper with 1 blade you can usually strip only the outer jacket. There are of course variations on the above, but these are the most common combinations. Also, some coax strippers are equipped with adjustable blades, always read at the product information how the coax stripper is constructed.

Accessories

.

A coax stripper is used to cut coax cable to size and then provide connectors. To cut the cable to size, a coax stripper is sometimes equipped with a cutting function. The tool is designed so that the assembly guarantees an interference-free connection. However: even a perfectly assembled coaxial cable can still experience interference. One reason for this is that the cable may be too long or there may be conditions in the building that interfere with reception. Sometimes it is better to use shorter cables and place an amplifier in between. We also have this type of amplifier in our assortment. Do you hesitate between buying long cables, assembling your own cable or buying short cables with an amplifier, please call or mail us.
