Hi Bill.
As far as know from the word of mouth, the radar was on the same site as the present radar and definitely not near Bobbyland Restaurant. In fact on the present radar site there is a cave which used to house the diesel generator and possible the personnel during air attacks.
In fact the Dingli Radar during the II WW was one of the triangulation system which the British Forces used, the other two were located at Tas-Sig Fort, near Marsaxlokk and at Wardija, between Mosta and St Paul’s Bay. It was only late during the war, 1942-43 that the first rotating antenna radar was developed by the British Scientist after they discovered that the Germans had such a system, but the British version was more refined. In Malta they installed the first system of rotating antenna radar at ‘Tal-Giordan Lighthouse’ in Gozo. The lighthouse building is still present.
Going back to Dingli site, considering that the Triangulation radar system needed some area for the curtain type antennas, Bobbyland area is not practical as it is not level ground and it is more than 50ft below the present radar level. Along Dingli Cliffs only Madalena Chapel, located towards Siggiewi is higher than the present radar site. Therefore I tend to believe more that the present radar site area was the actual site. When I first served there in the RAF during the early 60’s, the exhaust of the generator was still fixed with the cave’s roof and protracting out by the side of the cliff. When I left my responsibilities of Dingli Radar Station the caves where still as I found them in the early 60’s, rarely opened and I am not sure that present staff has any keys for them.
The present radar site has two adjacent sites which were used for Communications Receivers and for TACAN. These two extensions which are about 200 mtrs away from present radar site were always the property of the British Forces, so it makes me more convinced that these sites together with the present site were the locations of the three masts used for Curtain Radars.
If you visit Dingli village and try to find somebody who remembers the war and always lived at Dingli, they might give you a more solid prove.
I was always told that the present site is the one which has always been used.
Half way between the present site and Bobbysland there is a Military Post which is known as the ‘turret’, which probable was used by the military as a look out post. But this cannot be the site of WWII radar as it needed more than one mast.
I hope I shed some useful information, although I have no documented proof.
About three years ago I wrote a series of articles on History of Radar in Malta on a local e-paper
www.maltastar.com and the place I indicated for the Malta Trangulation Radar were Dingli Radar Site, Tas-Silg Fort and Wardija. Tas-Silg Fort is now being used as a dogs sanctuary.
I hope you will have a pleasant stay in Malta and the weather looks that it will be very favourable. In case you need some more information do contact me by email or on 79047718 while in Malta.
