COMMSCOPE LDF4-50A SureFlex Jumper
Product Installation Instructions
- Maintain a 2-inch straight cable length behind the cable. When handling the cable, do not hold the connector and bend the cable directly behind it. Instead, hold the cable adjacent to the connector to prevent stress at the cable/connector junction.
- Ensure that you do not exceed the cable’s minimum bend radius. Refer to the Single Bend Radius Table provided:
| Cable | Radius, inches (mm) |
|---|---|
| FSJ1 LSF2 | 1.0 (25.4) |
| FSJ4 / RSJ4 | 1.25 (31.8) |
| LDF1 LDF2 | 1.5 (38.1) |
| LDF4 | 2.0 (50.8) |
Note: To achieve the single bend radius, a mandrel may be required.
- Route and form the cable in place before attaching the coupling nuts.
- When positioning the cable, do not twist it.
- Do not attach the connector coupling nut of one jumper connector and leave the opposite end hanging unattached.
- Tighten the coupling nuts according to the manufacturer’s instructions or the Connector Interface Type provided below:
| Connector Interface Type | Tightening Torque |
|---|---|
| 7/16 DIN | 18-22 lb-FT (25-30 N*m) |
| Type N | 15-20 lb-IN (1.7-2.3 N*m) |
| 4.1/9.5 DIN | 88-132 lb-IN (10-15 N*m) |
| 4.3-10 | 44-70 lb-IN (5-8 N*m) |
| NEX10 | 35-44 lb-IN (4-5 N*m) |
Note: The connector interface threads and O-rings are designed for mate ability without any supplementary treatment. The use of supplementary lubricants/oils will void the warranty and may affect the performance of the connector/assembly.
Installation Instructions
Installation of HELIAX® Jumper Products
- Maintain 2-inch straight cable length behind the cable.
-
Do not hold the connector and bend the cable directly behind it, rather hold the cable adjacent to the connector to keep stress from the cable/connector junction.

- Do not exceed the cable minimum bend radius.
- Note: Requires use of mandrel to achieve single bend radius.
- Route and form the cable in place prior to attaching the coupling nuts.
- Do not twist the cable into position.
- Do not attach the connector coupling nut of one jumper connector and leave the opposite end hanging unattached.
Tighten the coupling nuts per manufacturer or industry specifications
- Use of a torque wrench on coupling nut is recommended.
- Use two wrenches. Place the torque wrench on the coupling nut, while simultaneously keeping the connector front body stationary using a second wrench. This will properly activate/compress the sealing gaskets to keep moisture out and allows for the most consistent and best possible electrical results.
- On site, under-torqued coupling nuts are a leading cause of sweep difficulties.
| Connector Interface Type | Tightening Torque |
|---|---|
| 7/16 DIN | 18-22 lb-FT (25-30 N*m) |
| Type N | 15-20 lb-IN (1.7-2.3 N*m) |
| 4.1/9.5 DIN | 88-132 lb-IN (10-15 N*m) |
| 4.3-10 | 44-70 lb-IN (5-8 N*m) |
| NEX10 | 35-44 lb-IN (4-5 N*m) |
NOTE: Connector interface threads and O-rings are designed for mate ability without ANY supplementary treatment to threads or O-rings. If any type of supplementary lubricants/oils are used, the warranty will be void, and connector/assembly performance may be affected.
