After you try all of the suggestions, go to fundamentals using a ruler.
I bought an ARROW 146437-10WBP in 2011, never used it until 2012, when I found a serious VSWR workmanship flaw in the 2011 ARROW products.
2m VSWR sucked and I could not adjust it in no matter what I did. See my files in: https://groups.yahoo.com/neo/groups/HAM-SATs/files/Antenna%20-%20Commercial/...
What I discovered is the 2m Driver gamma-match wire was 1.00" too short (per ARROW actual documentation). Upon verifying this with ARROW they sent me a new 2m driver element since we cannot unpress the pressed in BNC connector to change the wire.
My advice it to measure ALL per ARROW documentation especially the gamma-match wires - who knows maybe ARROW messed up, again!
Also the ARROW Diplexer is max 10W, be carefull not to go much higher in FM!

Pre Tim arrow elements were constructed with hollow arrow shaft crimped to threaded ferrules. Whoever did mine used the wrong crimp die. 75% of the elements inspected had fractures.
Kept a few for example if anyone wants pics.
Bought new elements from Tim. Replaced bad ones. Problem solved.
They preferred to fail FAR, FAR away from home.
