2 Be sure that connectors are tightened to correctspecifications. Use torque wrenches if available. Becareful not to over tighten.* For N male solder connectors , use the pin align-ment tool to check the inner Connector forstraightness. Adjust it, as necessary.** For N and DIN solder connectors , verify pin depthusing a depth gauge. Adjust the inner Connector , asnecessary.** Make all cable bends before connecting mating connectors carefully to avoid crossthreading.* Positive Stop connectors do not require use of a torque wrench.** Not required when using captivated connectorsSP5042312 August 2004 Page 1 of 2 General TipsSupplements the Installation Instructions provided with your HELIAX connectors . Be sure the Connector is loose threaded no morethan 1/4 turn. The foam dielectric must be separated from theouter conductor and pushed toward the innerconductor.

3 Do not use a razor or sharp knife toremove the foam. If you have trouble pushing the Connector onto thecable, remove a little of the jacketing. AndrewOnePiece connectors seal on the outer conductor,not the jacketing. When you initially tighten the Connector :- Push the Connector toward the cable with one hand- Keep pressure on the Connector and use theother hand to turn the clamping nut- Hand tighten and do not turn the Connector body(the portion with the interface)- After hand tightening, pull the Connector towardyou to to determine if the internal clamping mech-anism has engaged the outer conductor. If theconnector is attached correctly, it will not come off. To tighten the Connector , hold the Connector body inplace and do not turn it turn only the clamping nut(the smaller part of the Connector , where the openingfor the cable is located). After the Connector is tight-ened with wrenches, it should not spin on the for OnePieceTM ConnectorsPUBLICATIONA ndrew Corporation10500 W.

5 Refit or resolder ifyou find any of these problems: Pins not aligned with the inner conductor. Pins mustbe parallel with the inner conductor. Burned or melted foam dielectric caused by exces-sive heat settings or excessive soldering. This willaffect cable performance. Solder has a dull finish and traces of flux. Thesolder should be shiny and with no flux to provide agood electrical path. Solder should fill the solderholes and form a bead around the end of the :Use Rosin core flux solder coil: 63% tin, 37%lead, flux weight Use " solder for largerdiameter inner connectors and " solder forsmaller diameter inner connectorsTips for Solder Connectors90 Outer ConductorInner Connector PinSolderBeadSolderHoleDeburred InnerConductorPin Cu
