PL-259 And BNC Double V-Jaw Coax Wrench
This is a flat 153 mm double-ended wrench with a 60° V-jaw at each end. The large jaw is 28 mm wide at the mouth and wedges round or hex coupling nuts from about 10 to 26 mm, which covers PL-259/SO-239 and N connectors. The small jaw is 16 mm wide and takes about 5–14 mm, for BNC, SMA and F connectors. Because the V grips by wedging, no exact nut size is needed. You can snug and loosen coax at an antenna or radio without crushing the knurl with pliers. It prints flat, 8 mm thick, so the turning load runs along the layers, and it has a 5.5 mm hole for hanging it on a peg.
SDR Dongle Upright Antenna Stand
A weighted 90 mm base with a 55 mm tall sleeve that holds a USB SDR dongle (anything up to 32 x 17 mm in section) upright, so a telescopic whip on the MCX/SMA end can't pull it over. The USB extension cable's socket sits on the desk inside the open-bottom sleeve and leaves through an underside trench. An M3 heat-set insert takes a nylon thumbscrew that clamps thinner dongles. Three 4.5 mm holes let you screw the base to a shelf.
Wire Dipole Antenna Center Insulator
Centre insulator for a wire dipole or inverted-V: a 140 x 76 mm ribbed plate with a wrap-post cleat on each leg (3.8 mm entry/exit holes for #14 AWG THHN at ~3.4 mm OD, around a 7 mm post) so the antenna tension is carried by the plastic instead of the solder joint. The 42 mm coax tail has three zip-tie stations (3.0 x 5.5 mm slot pairs on 18 mm centres) that strain-relieve RG-58, RG-8X or RG-213, and the top tab carries an 8.4 mm rope eye plus two M4 clearance holes (4.5 mm) for bolting to a mast plate.
Mast Pipe Enclosure Saddle Clamp
A 72 x 80 mm mounting plate with two 90-degree V-jaw ribs spaced 50 mm apart that cradle a 20–48 mm OD mast pipe (3/4 in to 1-1/2 in conduit or fence rail) and pull it in with two standard 12.7 mm stainless worm-drive hose clamps threaded through the moulded band tunnels. The V-groove plus the 50 mm rib spacing stops the wind-twist you get from U-bolts alone; the plate carries four M4 clearance holes on a 56 x 40 mm pattern for a junction box or printed LoRa/solar node enclosure and an 18 mm centre pass-through for a cable gland or drainage.
Dual SMA Bulkhead Antenna Mount
A two-position bulkhead bracket for SMA / RP-SMA panel connectors: two 6.6 mm bores on 24 mm centres through a 4 mm deck, so a standard 6.35 mm bulkhead jack and its nut land flat with the antennas vertical. Gusseted L-frame, 54 x 44 x 44 mm, bolts down through four M4 clearance holes on a 42 x 30 mm pattern, with a pair of 3.2 mm zip-tie slots that take pigtail strain off the connectors — a replacement for the snapped antenna mount on FPV goggles, ground stations and receiver boxes.
