I don't think you need to break them apart, from what I remember. You can unscrew the internal element and SO239 from the bottom of the assembly...

Re: Diamond X-30 Tuning
That's very true, usually the "guts" and socket can be withdrawn out of the bottom metal "hub", with the removal of the odd grub screw or two!FakeJake wrote:I don't think you need to break them apart, from what I remember.

It's how they final assemble them in the first place, as opposed to gluing the fibre glass bit onto a sealed bottom block unit!
I have had many Diamonds, Comets, Moonraker etc. amateur radio white sticks apart for repairs in the past.
Only one I have ever come across "fully sealed" and not easily disassembled, was a "Decca" branded, VHF marine radio white stick.
But I am sure there must be others.

Re: Diamond X-30 Tuning
The Diamond X-30 is pre-tuned I would not try and alter the antenna. I assume you have calculated the length of coax so it is also resenant on the frequency. It should be in equal half waves plus a quarter and it depends on the coax used due to the volosaty factor, exactly what a half wave length should be. Might I suggest you visit M5BXB web site it has loads of information including a coax calculator, that can be down loaded and used at any time. Once you have your coax resend the the SWR will drop dramatically. I use the X-300 with similar SWR readings as you, as I as using a random length of coax, Steve (M5BXB) gave me the calculator and I trimmed my LMR 400 to the nearest length which worked out to 18 Half waves plus a quarter, my SWR is now 1.2.1 over 2 meg.
