minibend®, microbend® and mini141® Frequently Asked Questions

Bending & Flexing Questions

How tight of a bend can
minibend® handle?
±180° over a 0.20" radius.
(90° over a 0.15" radius once only) 
How far back from the SMA connector can I bend the cable? 0.590" from the face of the SMA Nut. 
(0.540" if  0.20" bend radius)
Can I add a marker sleeve?

Where can I locate it?
Yes, but do not violate the minimum bend radius of the minibend®. Marker sleeves and Brady Labels™ are not as flexible as the minibend®.

If they are located too close to the connector the cable could be overstressed by too small of a bend radius. To avoid this, locate the marker sleeve at least 0.40 inch from the back end of the connector.
How tight of a bend can
microbend® handle?
±180° over a 0.06" radius. 
How far back from the SMA connector can I bend the cable? 0.450" from the face of the SMA Nut. 
Can I add a marker sleeve?

Where can I locate it?
Yes, but do not violate the minimum bend radius of the microbend®. Marker sleeves and Brady Labels™ are not as flexible as the microbend®.

If they are located too close to the connector the cable could be overstressed by too small of a bend radius. To avoid this, locate the marker sleeve at least 0.13 inch from the back end of the connector.
How tight of a bend can
mini141® handle?
±180° over a 0.33" radius.
How far back from the SMA connector can I bend the cable? 0.770" from the face of the SMA Nut. 
Can I add a marker sleeve?

Where can I locate it?
Yes, but do not violate the minimum bend radius of the mini141®. Marker sleeves and Brady Labels™ are not as flexible as the mini141®.

If they are located too close to the connector the cable could be overstressed by too small of a bend radius. To avoid this, locate the marker sleeve at least 0.70 inch from the back end of the connector.
How many times can I bend the cable? ±90° bends over a 0.25" radius a minimum of 30 times without degradation in VSWR or Insertion Loss. Larger radii and smaller bend angles will allow more bend cycles. 
What do you mean by a "true flexible" cable? minibend®, microbend® and mini141®, unlike "conformable" coaxial cables, can be repeatedly bent as defined in questions 1 & 2 at any point along the length of the cable without damage. However, the standard minibend® and microbend® cannot tolerate repeated torsional stress by rotating or twisting around a fixed point. See our minibend R which is designed to tolerate higher cable retention forces. 
Is there any "anti-torque" feature built into minibend® and microbend® to prevent the cables from rotating while the SMA Nut is torqued down? minibend® and microbend® do not require any external "anti-torque" features. Other SMA Male connectors use a Snap Ring to retain the SMA Nut to the connector body. After the Nut is assembled hand tight to the mating connector, the body will rotate up to 15° while the SMA Nut is torqued (the Snap Ring acts as a bearing surface which allows more movement). minibend® and microbend® connectors do not use Snap Rings so they rotate less than 5° while the SMA Nut is being torqued. 
How far can I rotate the
minibend® and microbend® after bending the cable and torquing the SMA Nut?

for all minibends except minibend R

minibend® and microbend® were designed to be bent close to the back end of the connector on a tight radius.

Do not rotate or twist the standard minibend
® cable after the connector is mated and torqued down. See our new minibend R which is designed to tolerate multiple ±90° bends at the cable/connector junction.
