Hi G

Decided I would go measure the ant, rather = than quote=20 what it was going to be. (Would I lie to you baby).

10W = RF
Ant.=20 Marconi inv. L. Vertical section 3.5m -  Top section single wire 7m = long.

Absorption Factors:-
Metal core clothes line 400mm from = Loading=20 coil, 400mm from vertical wire.
9m steel mast with VHF antennas 2.5m = from=20 feed point.
6m ally mast with 4m antenna & TV ant. 2.2m from feed = point
House and wiring 2.5m from feed point
40m Doublet and feeder = 2.2m=20 from feed point
8x6 aluminium greenhouse under Top Wire far = end
Top Wire=20 crosses 40m Doublet wire 200mm from its end 100mm vertical = clearance.
Top=20 Wire ends 100mm from 6.3m steel mast
6.3 steel mast emerges from top = of plum=20 tree 5m tall.
Holly tree 5.5m tall 5m from end of Top Wire
Active = antennas=20 horizontally 5m from Top Wire
7/8 28MHz vertical 7m horizontal from = Top=20 Wire
Surrounded by Houses with overhead mains electricity feeds on 3=20 sides.

Can I sat it was shoe horned in.
If you can work out a = loss=20 figure I would appreciate it.
