Telescopic 8m Mast /Aerial, complete with base ,pins and guy ropes.

 

Make good flag pole

Looks like a 27' Larkspur era mast.

Should have a great big insulator to go at the base for when it is used as a vertical radiator,but yes Larkspur from looking at rhe pigtails on the guy ropes and the big stakes for them,lucky you have the c spanner for locking it off as these often get mislaid,if you put it up just watch it does not slide down a section as it will make a mess of the flap of skin between thumb and forefinger(no i haven't done it)

Yep 27ft mast, larkspur era, it does indeed have the vital 'c' spanner, but does it still have its hammer?

Not just the hammer! :D

 

That mast is infamous for having the rigging kit that weighs more than the mast itself.

 

From memory the full kit list is:

 

Mast, telescopic, 27-ft (check that it has the aerial rod clamp fitted at the top).

Carrier for mast.

6 x stay assemblies (guys) - these are terylene and non-conducting so don't need insulators.

Halyard - with pulley for use with wire aerials (e.g. 100-ft No.5) probably not terylene.

3 x 18-in steel angle pickets with S-hooks.

GROUND SPIKE - the heaviest item after the mast itself.

Insulator (for use as a vertical aerial)

Flat (vehicle roof, solid rock or soft/sandy ground) base - the flat one with eyebolts at the corners for tying it to the vehicle roof so it doesn't slide about.

2 x Pins (pegs?), Aerial, 'A', for anchoring the flat base when used on the ground. (pre-WW2 design, still in use!)

Spanner for locking rings (originally only for releasing them, but later for tightening as well after the self-collapsing mast feature became known).

4-lb club/lump hammer - the third heaviest item in the kit.

Spare shaft for club hammer (removed from kit after the Elves who drink Safe Tea[1] prohibited hammer repairs, even by REME & ABRO!)

Metal "Working instructions" plate.

Holdall to contain rigging kit.

 

The mast is essentially a redesign of the WW2 Canadian "Mast, Telescopic, 34-ft" with some improvements but considerable added weight. (It lost the 'pipe union' mast joint in favour of a threaded plug, gained rather better pickets and guys, replaced the vulcanite base insulator with a beefed-up version of the original (far too fragile) ceramic one, and got an even heavier ground spike than the Canadian forged steel one - but it was still entirely possible for the users to bend the blasted thing!) You do need a vehicle to cart the thing around, of course.

 

You can stick the 14-ft whip (for the WS62), 16-ft of 'F' rods (WS19 or Larkspur) on top for HF, or one of the 'Elevated Aerial' kits on top (for Larkspur VHF sets) as required.

 

Unlike the 34 (or 32) foot sectional mast, it is entirely possible for one person to erect and dismantle this mast, provided there's not too much of a wind blowing.
