Marconi Tee Aerial

UPDATE: in 2013 the Marconi Tee antenna was retuned to the new 630-metre amateur radio band as ZL1ZLD ceased operation on 512 kHz (600 metres).

As part of bringing 500 kc/s back to life, members of the Musick Point Radio Group built a Marconi Tee antenna, and erected it between the station’s two towers, a span of 90 metres, on 23 September 2009.

The antenna spreaders were made for us by Kilwell Fibretube of Rotorua at a generous discount.
