We believe this requires a crimping tool with a hexagonal die of 0.429" (10.9mm). We already have the replacement RP-TNC plug.
Alternatively we would seek to borrow or - if we have to - buy an additional 50ft (15m) of low loss RP-TNC-terminated cabling to enable us to temporarily relocate the aerial from our Cisco Aironet 1200 wireless bridge aerial whilst scaffolding is in place from now until August 2017.
If you can help us in either matter, please contact us on firstname.lastname@example.org, or ring Derbyshire Wildlife Trust: 01773 881188.
We've known for some time now that the cathedral's nave roof has been leaking. Temporary repairs were tried a year ago but only with partial success. Eventually it became clear to the cathedral authorities that a completely new roof would be the only way to solve the leaking problems for good.
So the Cathedral submitted a funding bid to the WW1 Cathedrals Repair Fund for £750,000 to carry out this work, and was delighted last summer to receive the go-ahead.
This has given us plenty of time to work with the Cathedral staff, and liaise with Natural England officers, to ensure the best outcomes for the building as well as its breeding peregrine falcons. The law says it's illegal to disturb peregrine falcons once they have started nesting, so it was important that Natural England was happy with the timing of the 9-month work that was being planned.

Roof lead removal and replacement will then take place entirely under the sheeting from March through to July. As well as keeping the exposed roof dry, the sheeting will prevent the peregrines above seeing anyone working below.
|Scaffold in place along the south side of the nave, 9th January 2017.|
That's the theory anyway. A long spell of snow might delay the initial scaffold and sheeting works but hopefully by only a week or so. If the worst came to pass, the birds might simply decide not to breed this year (maybe they could do with a year off?), but the work will have been done with full regard to the law, and scheduled with the best of intentions to reduce any potential impact.
Both male and female peregrines have been at the cathedral since 2005 and probably even before then, So they are getting on in peregrine years now. At some point we would expect one or other parent either to die from natural causes or perhaps become infertile with old age. So having a year with no eggs to lay might just extend the female (the falcon's) life span....and may just happen naturally at some time.
Hopefully their desire to produce even more young (they've reared 37 so far since 2006!) will ensure that they ignore the works below them and nest again. We know that noise doesn't bother them - it's the sight of people that does -whether it's a gamekeeper with a gun or a builder with a wrench. By keeping the two visually separated, we think they will still be minded to nest here again. Egg-laying takes place normally at the end of March or the first week of April. Fingers crossed that they do nest successfully again.
We've had meetings with the contractors yesterday who are aware of the birds presence and needs and will be doing everything they can to minimise disturbance throughout. Already, scaffolding has been erected along the south side of the nave. The north side will follow and then scaffold on the edges of the roof will eventually support the opaque, heavy duty plastic sheeting which will entirely envelope the whole of the nave, allowing the lengthy works below to continue unaffected by the weather.

PS: We've invited Alex Rock from the cathedral staff to update us on the work as it progresses, and will post his updates here.
PPS: ON Tuesday 10th, we spent a day in the cathedral tower with Tim from Connect Derby, configuring our cameras equipment on a completely new network equipment. So, we're now one step further forward to getting back live webcam pictures, with a bit more work still to do to allocate IP addresses and allow Network Webcams to pull video from our equipment again. Sadly, we're also one step backwards with a fault developing in the aerial cable from our 2.5GHz Cisco 1200 series wireless access point - hence the appeal for help at the top of this post.
