How to get a coax cable through a cavity wall (or improper use of knitting equipment)

For a while I'd been wanting to reroute the coax from the Butternut HF6V to the shack. Where was it going before, I hear you ask? Well, the lounge actually... it's a long story.

Got around to the job yesterday and put a new coax run in up the garden, secured it to the fence and neatly tacked it up along the side of the house. When we put the V2000 vertical up on the house the other day, we drilled another hole into the shack to take this coax.

However, I had a very frustrating half hour or so trying to get the coax through the hole (which it turned out was not quite straight) - the coax kept missing the hole at the other side of the cavity and curling around.

Julie seeing my exasperation suggested I had lunch whilst I worked out a plan. Over a prawn mayo sandwich I noticed a number 8 knitting needle sitting on her desk....

Once replete, I marched outside with the knitting needle, a knife and some insulation tape. I stripped back the outer of the coax and the screen, leaving the inner of the coax to the same length as the knitting needle. I then taped the end of the coax as tightly as possible to the sharp end of the knitting needle. And poked!

The needle and coax went through the hole first time. From the inside, I undid the insulation tape from the tip and pulled the coax through as far as it would go. Then I went outside and gently retracted the knitting needle (I really didn't want the coax to follow it!).

Back inside and I was then able to pull the coax through into the shack fully! And hastily, I rinsed the knitting needle to ensure it was once again fit for knitting!

So, I can now play HF should I wish. Currently the Butternut vertical is connected to the Anytone AT-5555. More on that in a separate post.

If you don't have a knitting needle handy, a straightened metal coathanger may serve the same purpose.
