Quick fit when you feed through cables of a ship , it is often necessary to remove the bulky connectors for the cable through tight spaces , or it may be necessary to extend the cable and connectors suitable coupling parameter is ideal. Solder connectors can be complicated and requires specialized crimping tool that many people have , so using a very tempting transparent RAF connector supplies quick fit .
However , I learned a lesson today that quick fit I hope others can learn . I had not met before this type of connector ( see photo above) and the idea is to place the coaxial cable securely inside the quick connector , where a strong quick fit rod press center at the inner conductor cable . After pressing the small screw shown in the image above and cut through the outer insulation and makes contact with the driver , the outer sheath of the cable. At first glance, this seems a very Cleave idea quickly, but as I was to discover this type of connector may create more problems than it solves quick fit .
The ship had visited one of our Class B trans ponders IT' which gave a high SW reading diagnostic software praxis quick fit adjustment . ROMS is an integrated self-test IT' where energy sent to the antenna is measured and the measured power " reflected " down to the antenna. In an ideal world all the power quick fit sent to the antenna must be returned to the fast air link , but this is never the case , and a small amount is always reflected back IT' . If there is a power antenna or a short or open circuit in the antenna and the SW is very high ( > 5.1) and activate an quick fit alarm cable.
This particular boat has had a large number of these connectors Erecting opportunity to expand the AIDS antenna , but seemed well, so I started by quickly connecting a VHF emergency antenna directly quick fit IT' . Voila, the next show AIDS ( every 3 minutes in a standing position) reading ROE achieved rapid adjustment very healthy 1.2:1. The AIDS antenna installed is mounted on the mast for the replacement would be a pain , so just to be sure they thought I would check out the piece of antenna that had been quick fit placed on the cable wire. Test the continuity and rapid isolation CC showed a short-circuit between the inside and outside of the extension .
Further mount connectors quick review , I found that the removal of one of them , the short is gone. My only conclusion is that it quick fit is the small screw which is intended to come into contact with the outside screen was short tight inner and outer conductors or wire cutter was used blunt and badly cut a few strands of the shield had short to inside. Anyway the fault was found and quickly connected to the connector "Quick Fit" for the cable. Just to be sure , I repeated the test continuity and insulation and this time I showed short has disappeared, but it was soon no continuity in the internal connection .
In total, I tried to redo the "Quick Fit" three or four slots and each time there was a continuity in the central conductor and at the end I gave up and replaced everything with the terminal I quickly never had a problem with . You might have to spend € 10 - w 15 in a crimping tool ( see below ), but if you regularly RAF connections or simply the best connection possible, so I really recommend the quick installation crimp connectors quick fit.
