I use an antenna as a back up to our satellite dish. However it picks up a slight herringbone pattern. There are no cars or machines running nearby. I actually replaced the antenna and the coax and checked cleaned and tightened all the fittings and it's still there. Any ideas? Tx

Herringbone is usually interference from another transmittor, probably radio, is it on all channels? probably, with one worse than the others.
It would be usefull if you could supply your postcode, the first group of digits would be enough, as it is possible to check out reception conditions in your area.
The above links should help a bit, but then you need to find out about radio transmittors too, you may have more luck pointing at a different transmittor (if possible). It might also be an illegal transmission or taxi firm but I suspect it will be a legit transmittor. Again without a postcode to get the local info it's hard so give much more assistance. By the way I did have a similar problems solved by pointing at a different transmittor.
Also you could get a freeview box, (for less than £30) and go digital.
The herringbone interference is highly unlilkely/will not affect the digital signal.
Better coax etc, will make no difference, as you found, as you just get a better TV signal and a better herringbone intefernce too so no overall gain.
