The N Connector Bracket is an optional upgrade kit to convert the DG8SAQ VNWA 3 or 3EC for use with the popular N series connectors in response to requests from existing VNWA users.

Based on a design by Dom F1FRV, the kit consists of an anodized aluminium bracket fitted with 2 quality N Jack to SMA Plug pigtails which are screwed into the VNWA front panel SMA Jacks.
The bracket comes with a fitted Aluminium front panel and a 2mm hex key tool to carry out the conversion.
Use of a 0.5Nm torque wrench is recommended when tightening the SMA plug connectors to the VNWA, but this is not essential provided care is taken not to over-tighten these connectors.

The N bracket conversion is reversible and the VNWA can be changed back to normal SMA Jackets whenever it is required again.

Note: The standard VNWA with SMA connectors shown in the photo is NOT included in the order for the N Bracket, but must be purchased separately.

1 pc assembled N Bracket complete with fitted N - SMA pigtails and front panel

8 pcs 3mm dia x 8mm long hex screws

6 pcs 3mm 19mm dia Rubber Feet 

1 pc 3mm hex tool

N Conversion Kit Fitting procedure:

The conversion should take less than 20 minutes and consists of the following steps

A. Check kit contents are as listed

B. Make sure the VNWA is functioning correctly before carrying out the conversion.

C. Remove the 8 hex screws on each side of the VNWA using the hex tool supplied but make sure you do not remove the VNWA covers in the process.

D. Fit the VNWA in the N bracket and replace the original hex screws with the 8mm long hex screws supplied.  Do not tighten the screws at this stage.

F.  Carefully fit the SMA Pig tail cable Plugs to the VNWA front SMA Jacks and tighten the connectors to a recommended value of 0.5Nm, this is a slightly higher than when tightening by hand for an average person. Be careful not to over tighten the SMA plugs when using other tools than the recommended 0.5Nm 8mm Torque wrench!

E. Fit 2 pcs Rubber feet to the bottom front of the BNC Bracket.

F. If your VNWA is fitted with the smaller 13mm dia rubber feet, then remove these feet and replace with the 4 pcs 19mm dia rubber feet supplied.
    Note:  Newer VNWAs are already shipped with the 19mm dia rubber feet - these VNWAs do NOT need the rubber feet replaced.

G. Place the VNWA and Bracket on a flat surface and align the position of the VNWA within the bracket so all 6 Rubber feet are aligned flat on the surface before tightening the 8 hex screws.

H. Test the converted VNWA for correct operation.

This completes the N Bracket conversion process.
