Goltone No-Mast Aerial

The latest product of the wireless side of the business is the Goltone patent No-Mast plate aerial.
This consists of a rectangular wooden framework about 2' by 2' 6", in which is mounted a sheet of perforated metal finished in bronze. To the centre of the metal sheet is attached one end of a coil of wire which serves as the down lead. This wire may either be ordinary heavy rubber-covered wire or a 5o ft. coil of Negrolac, the latter type costing 6s. extra. The attachment at the centre is made very strongly so that it cannot pull away or corrode if the aerial is used out of doors. In addition to the rectangular plate aerial, a cross of wood is supplied for mounting purposes. This cross is first mounted on the brickwork or chimney of the house.

Test Results

We installed our sample of the aerial under a tiled roof 11 miles from Brookman's Park, where it is giving good results. A good deal of the pick-up is on the down-lead, of course, but the plate is evidently acting in a capacitive fashion, not unlike that of the original Hertz plate aerials and is definitely adding to the efficiency. The latter is rather greater than that of a small aerial previously used inside the roof. As far as we can judge, the selectivity is as good as that of the small indoor aerial.

The No-Mast has a great advantage in that it is inconspicuous and occupies very little space, making it very suitable for use by flat dwellers and others who cannot or do not wish to erect an ordinary aerial. Also, mounted flat against a wall or chimney, it is not likely to be blown down in a storm. The price is 24s. (with rubber-covered down lead) or 30s with a 50' Negrolac down lead.
