Diamond X-50 install

(For what it's worth)
Still in the pack. This is actually Meg's; I already unpacked mine and tested it on the floor. We bought from Andrews and shared freight (Strictly were out). These had S0-239; they were out of N-type.
4.5dB on 2m and 7.2db on 70cm. SWR is less than 1.2 : 1 from 144MHz to 147Mhz and about 1.4 above 147MHz. On 70cm it's about 1.3-1.5 from 433-442MHz
Finally installed properly. I had it on the short mast my ¼wave was on and it was on a bad lean (maybe 7-10°). Turns out the roof beam the mast is bolted to has a twist. Still has a slight lean. Now has 2.5m of 40mmØ reducing to 32mm reducing to 2m of 25mmØ then the antenna on top. Replaced the RG58 with a 15m pre-assembled RG213 with N-types either end and a N-type to PL-259. The coax runs up the inside of the mast and the connector just barely fits up the 25mm section. Mast joins are simply the upper section slid inside the lower section with a SS hose-clamp stopping the upper from sliding all the way down. Then sealed with non-corrosive bathroom sealer and wrapped with a couple of layers of self-amalgamating tape. No, I didn't install the TV antenna and it is on a shocking lean.
