If a your area is surrounded by tall trees or where multi-path reception is experienced, it is expected that digital signal quality to go up and down as the trees or aerial move in high winds. Wet leaves attenuate UHF DVB-T multiplex signals even more. If you have tall trees directly in line to the transmitter, you may get problems with reception dropout under adverse weather conditions. Trees can attenuate the DTT signal considerably especially when leaves are wet.

Not DVB-H, DVB-T (Not Handheld but Terrestrial).

This thing is going to be interesting. I wonder how DTV is going to deal with the shadows problems in CBD area and around tall buildings. On analogue systems, this created a phase lag ( if I remember the correct term )  with a reflected wave, causing "shadows" on signal received. Digital will just cancel each other out as noise and DTV tuner unable to re-construct stream, leading to no signal or blank screen. Will line of sight become too important. What about trees? SNR levels become critical...  What do you guys think? :-)
