Recent queries about internal dimensions for sizing the pcbs suggest that you should subtract about 2mm from the quoted external dimensions

Please note I do not make these boxes they are imported from Germany to the UK and a custom box size requires a minimum order quantity of 20 units, so this is generally not economical, unless you are marketing a project.

Eurocard sized
1000111  162 x 102 x 30mm.......................£8.00ea.
1000161  162 x 102 x 50mm.......................£8.50ea.

Other sizes can be ordered to suit your requirements, please ask. Please note it is easy to make boxes of a different, shorter, length from these by pruning the long side wall. You are of course left with a "too long" lid but at least you have only one flange to fold to alter that, after cutting the lid down. If fact, reforming the lid flange is not actually necessary and the cropped lid can be secured with a couple of dabs of solder.....not as pretty though....I am sure our German friends would not approve !

Other sizes not stocked.....at present ...Please ask I can add your requirements to my next order

Diecast Aluminium boxes (new)
111 x 60 x 30 mm................................at £6.00ea 

Masthead mounting enclosures (Schubert) 
I am stocking two sizes of the Schubert Masthead enclosures, the Medium and Large
These consist of a plastic "Hood" and "L" shaped base-plate drilled for a mast clamp
self-tap screws, and a mast clamp Medium pictured  below

Medium size Masthead assembly...............................................................£20.00ea.
Large size Masthead assembly...................................................................£30.00ea

Note that these can be supplied without the 60mm  mast clamp for £13 and £23 respectively

Filter boxes   (Popular for G4DDK wideband pre-amps)

Filter boxes (Tin-plate). These come in two sizes, they have the same width and height (20mm square) but are available 37mm and 55mm lengths. They are pre-punched at both ends to take BNC connectors (with the alignment "flat") and can be supplied as a kit with either grounded or isolated BNC sockets (ask)
They are ideal for isolating transformers and small in-line filters or attenuators, or even couplers !! These are suggested for use with the wideband amp pcb kits that Sam G4DDK sells

FG2P 20 x 20 x 55 (punched BNC)........................£2.60ea.
For those who want a different connector I also have un-punched boxes now in both sizes in stock
FG1  20 x 20 x 37 (un-punched)........................£2.00 ea.
FG2  20 x 20 x 55 (un-punched)........................£2.50 ea.
FG3P 20 x 20 x 74mm (punched for BNC).........£3.00 ea. (Much more room to mount components between the BNC spigots.)

Coax adapters. (new) These are not of the highest quality but are adequate for most purposes, I suspect the insulation is Polypropylene rather than PTFE
I am running these stocks down as they are not really microwave  quality
N-Female to SMA-Female.......................at £2.50ea.
N-Male to SMA-Male.............................at £2.50ea.

and we reckon they are good to at least 4GHz.

I have a stock of sockets in SMB and SMC in sealed packets please ask. 

I have also some Reverse SMA (WiFi) to standard SMA adapters please ask these are £4.00 each

Quality 10MHz HC49/U crystal (Farnell part 103-887) 10ppm tempco ................................at £1.50ea.
Though not cut for the appropriate temperature I am told these work well in John 's OCXO

GPIB / HPIB / IEEE-488 stackable interconnecting leads, There are used but visibly in good condition though there may be
a little surface rust on some of the fixing screws. They are "good makes" like IOTECH, Amplicon, RS Components etc.,
and all have a double ended connector at both ends. At this price they are not electrically tested !!
