Flat 50 ohm coax?

An old friend has just bought some coax off Amazon so he can feed his aircraft band RX feed though his window without drilling holes. It is very short with just the bit through the window frame being flat. Both inside and out you feed it with "proper" coax and connectors.

Now, I have never seen these for 50 ohm coax and not sure these exist. I expect there is a very limited market, but I guess they could be very useful for some people.

Coax cable

It is many years since I last bought coax (2012?), so I am a bit out of touch on prices, types and sizes. Come to think of it, I must have bought some low-loss coax when David G0LRD installed my 2m big-wheel, but I cannot recall where I got this from!

Every weekend, MLS has some special weekend deals and this week it includes coax and coax tools.

Coax losses

If you are like me, then you always want to know the loss of your coax at 6m,2m and 70cm, possibly higher I found this very useful table to compare various coax cables at different frequencies. You may have your own favorite table! If not, I hope you find this one useful.
