Panorama Antennas has its factory, laboratory and offices close to central London, at 61 Frogmore, which is in Wandsworth, south of the Thames between Putney Bridge and Wandsworth Bridge.
Turn into Frogmore from Putney Bridge Road (A3209) or Armoury Way (A3/A205). The A205 is known locally as the 'South Circular' road.
Be warned that Armoury Way is part of the 'Wandsworth one way system'. So if you miss the left hand turning into Frogmore from Armoury Way you'll have turn right down Ram Street (or Fairfield Street) and right again into Wandsworth High Street to get back into Putney Bridge Road or Armoury Way.
Trains to 'Wandsworth Town' are frequent and the journey time from Waterloo varies between 15-30 minutes. It takes about 5-10 minutes to walk from the station to Frogmore.
(Do not get a train to 'Wandsworth Common' - that station is too far away!)
The nearest London Underground station is 'Putney East', which is on the District Line. It is about 10-15 minutes walk away.
('Putney Bridge' tube station is about 30 minutes walk away.)
Frogmore is close to many bus routes including the following:
28, 37, 39, 44, 77A, 156, 170, 220, 270, 337.
