Looking for Enclosure

I am trying to find an enclosure similar to attached (with antenna, I know these are probably costume), or some people may remember the old mast top TV antenna pre-amp enclosures which also looked similar to attached which would have high IP rating.

Have looked through all IP67,66,65 on Farnell & RS but cant see any. Any help would be appreciated.

Enclosures that are just as effective but not nearly as pretty are available from a number of electrical hardware suppliers, at least here in the USA. The gray solvent welded junction boxes need only a suitable gasket to be quite weather-tight, but not quite hermetically tight. The best part is that they are relatively cheap. Also, mostly they come with mounting provisions, They would work well for a small amplifier on a tower, with the added advantage of being able to attach plastic conduit to protect the wires leaving.

I like mostly stainless or aluminum enclosures.
Aluminum exists as the four-corner pipe, my most beloved is 60x20 mm. The 6 meter piece cost about 20 Eur, so the 10 cm long piece costs 20 cents. In both sides are half-opened rail where to screw a covers screw or/and slide a PCB. Only last 5 mm on PCB then can`t use.

The same exists for AISI-306, at sizes of 45x15 and 60x20 mm But it has too thick walls, thus a case is bit too heavy.

Therefore I changed construction to AISI-306 0,5 mm thick steel plate, bend it, and weld a sewing with a TIG or screw. Fast, nice looking, very cheap. The 2x1 meter plate cost about 30 Eur and is mirror-polished.

In some rarer cases the good material is sewage pipe, the grey or white. Especially for high voltage systems inside, or systems with loudspeakers as rodent killers. Two feet over pipe perpendicularly, accurate covers and most of people never will say it was a sewer pipe.

Ouch, ya, about end-cups, the furniture shops has plenty of cheap but nice end caps for as round pipes as rectangular pipes. Using of them is more asy than cut a stainless cover, however may do as one as another.

And last, the electrical cabling rails are fine material where to put all the pcb You brew, buy a 3 meter rail for some 4 Eur, and there You have some 40 cases in. Them exists in some 10 different widths and heights.
The ends then be glued from the same material, but on thick white glue or thermically.

And last but not least is 3D CNC or 3D-print, what gives a brilliant results but takes a day for making and three days for drawing.

However for case of antenna fixing, the good results give a plastic round food cups filled by epoxy. After cup is taken off, epoxy may be painted or whatever one may want. The bad thing is - it is not openable. The good things is - its ultimate hermetic.

Thank you Janis for taking the time. I am well aware of the range of IP65,66,67 housing out there and various home made/DIY methods but for this particular project i am specifically after the attached photo housing which I havent been able to find as yet.
