Ah, interesting question, but initial response is no. is only a Light and doesn't carry the commercial multiplexes SDN/COM4, ArqA/COM5 and ArqB/COM6.
For which TV are carried on which , see -
Channel listings for Industry Professionals | Freeview

You haven't said how long you've had the problem! There are a number of possibilities.
1) Is it a problem you have periodically and has started again recently - since last Friday perhaps?
2) Is it a problem that is happening continuously, more or less all day and all night or
3) Is it a problem that comes and goes on (nearly) most days?

If 1) it's current weather conditions, you MIGHT get more reliable from an alternative transmitter (more detail in a moment and it might mean a change of )
If 2) Something that could be due to new/upgraded phone masts (you've got at least 11 near you!
If 3) Then an alternative transmitter may again be a solution.

Let's deal with 2) first as it's a short simple matter which you may suffer from and should be able to deal with. Have you had a postcard from Restore TV? - you should have but we know lots of cases where people haven't been sent one!
See https://restoretv.uk/post…ure/
If your current aerial is a then you are more vulnerable to this issue, if it's a newer Group K then that will reduce the potential issue, or if it's even an older Group A aerial which was all that was needed for it might help reduce the problem BUT ....
If you haven't already got a Filter (often called a filter), get in touch with Restore TV and request the Free filter. If you have any Amp/splitter to feed several TVs/boxes etc , the filter should be fitted BEFORE the Amp. If you have an external Amp, tell Restore TV - they should send an engineer Free of Charge to fit a waterproof one on your mast.
If the latter is the case then they could well deal with 1) and 3) as their job is to ensure you have as reliable reception as possible.

Ok. 1) & 3). You have possible reception in your postcode from 3 transmitters, Rowridge, Findon and and luckily you should have line-of-sight to all 3 assuming no direct local obstructions from tall buildings, trees etc.

There is a "however" - Findon, already mentioned BUT it should give the most reliable reception of those 3 PSB multiplexes.

Let's mention Rowridge next - is your aerial horizontal or vertical polarisation? (ie the rods or squashed Xs horizontal or vertical). This transmitter (one of very few) has both polarisations.
If Horizontal, then the reception of the PSBs is failry good, but the COMs are VERY variable to none for ArqA and the COMs are also lower for horizontal. Ther's also a Local mutliplex but you aren't predicted to get it.
If Vertical, then the PSBs are better, and so are the COMs as they are transmitted at the same power as the PSBs but still can be variable reception. (No Local mux on vertical).

Now Whitehawk Hill. The COMs are very much better and all but the PSB3/HD multiplex are better than Rowridge but still may give you reliable reception.

Note, all comments about reception are based on "predicted reception", so not an absolute guarantee!

Finally aerial direction (also Group and polarisation). Vertical polarisation is needed for the alternatives to Rowridge and is best for Rowridge (although no Local mux)
Whitehawk Hill also has a Local mux which you are predicted to get.

If you have an old Group A aerial for Rowridge, then it will be best replaced with a Group K (and maybe old enough it may have deteriorated connections and coax anyway).
A Wideband will be OK for all transmitters (apart from the vulnerability of from Mobile masts) BUT a Group K is best and should be used in an aerial replacement situation and should be high apart from maybe Findon which "might" be ok with medium gain.

For your postcode, direction for Rowridge is compass bearing is 255 degrees (15 degrees S of due W).
Direction for Whitehawk Hill is 87 degrees, pretty well due E.
Direction for Findon is 8 degrees, that's 8 east of due N.

that helps, if you have further queries, post back.
If you need an aerial installer, make sure they are recommended and knows your area (preferably CAI approved) and not a back street cowboy.
