THE TRANSMISSION GALLERY
BURTON (WINSHILL WATER TOWER)

| Rob returned to Burton and commented "I had only intended to get higher resolution pictures of the Tx colinear, but if I think I know what I'm seeing HP is now being provided by some kind of antenna lower down (anyone name it?) although I could easily be wrong. The main colinear has also had a height increase of a metre or so too, probably slightly improving coverage." Alan notes that the relay is low powered (40 W horizontal and 50 W vertical) but as well as covering Burton upon Trent and Swadlincote transmissions from this site are receivable over quite a wide area. |
| Viewed from the "front"... |
| ...and the "back" - the change is at the very top... |
| A horizontal component is provided from the square loop (most likely a Shively Labs model 6602B) with the vertical component using a JayBeam end-fed dipole. |
| Six years later and Alan's photos show nothing much has changed... |
| The antennas are 47 metres above ground. Ofcom data shows the HP component has reductions of 1.8 dB on bearings 0, 90, 180 and 270 degrees - making the pattern slightly "square" rather than truly omnidirectional. Curiously the VP component is also documented as having a a very slight reduction in ERP - 0.2 dB on bearings 40, 130, 220 and 310 degrees. This suggests some interaction between the two antennas - but the overall combination is a good approximation to the ideal. |
| Not highlighted before, this slant-polarised yagi faces Lichfield. |
| At the time of Alan's visit work was in progress... |
| ...possibly involving one or more of these. The effect of the brick cladding and corner detailing is slightly spoiled by the rather more "industrial" appearance of the cable runs. |
