Is your aerial a wideband type? Mendip transmits HD on channels 33 and 35, which is outside of the range covered by a typical Group C/D aerial commonly used for the other services. You say you have a wideband aerial, but is it realy a true 'wide band' type? If not, that may affect the signal strength for HD at your TV set so that they are too weak. Check the strengths shown on each multiplex by your TV, the manual will tell you how.
The best solution is not an amplifier nor a second aerial but replacing the current one with a good log-perodic aerial that covers all the current and foreseeable future channels. You should aim for a signal strength of between 60% and 85% for HD services and no more than 85% for SD channels. At just 38km from Mendip you should be getting good signals, but the other alternative sources are much further away and don't give local service for the Yeovil area.

Nigel Shenton:
Take a look at the 'digitaluk trade' box at the bottom of your posting (or go to Coverage Checker - Detailed View to see what reception possibilities you have. Stockland Hill is a possible but with some multiplexes being variable. It is also some distance away so the signal strength may be variable due to atmospheric variations. Wenvoe is a non-starter and Mendip has the best options though the terrain plot shows possible obstructions at about 5 km out from you.
The best chance is to have you aerial mounted as high as possible, making sure the mountings and pole are strong and safe. That could enable the aerial to 'see' over the hills.
You best policy is to consult a local TV Aerial contractor for advice based on local knowledge.

Trees are well known to be able to cause selective reception problems, so I'm not surprised that only one channel is affected.
Check what signal strengths are reported for all the multiplexes on your TV set (the User Manual will tell you how). You should be aiming for at least 50% on SD and 60% on HD but not more than 85% on either. If your strengths are greater then you need an attenuator as suggested by StevensOnln1. If channel 60 is weaker than 50% then you may need to reposition your aerial, if possible, so it looks past the tree rather than through it.
If you put your full post code into this website, you can examine a mapping of the area and that will show whether any mobile masts are close enough to cause any problems. By all means contact at800 and if they consider it wise they may well provide a free filter to put in your aerial lead behind the TV set (use an extra flylead so the weight of the filter does not 'hang' on the aerial input socket).

Like StevensOnln1 and several others, I am a regular contributor to this website aiming to assist those having reception problems. Just because some foolish person decides to submit an inappropriate post does not mean any of us like it, some are particularly obnoxious. But as the website is run by Briantist, no one else can delete the inappropriate postings. That they sometimes remain for some time does not mean the site is out of commission, merely that the offending post has not yet been removed as Briantist may well have other priorities for the time being.
The reality is that some people think it is appropriate to offend others and make unsuitable statements in the digital media, just look at whats on Twitter, Facebook, etc. A large proportion of what I have seen there are inappropriate and sometimes downright wrong. Think of the stories about 'false news', where do those stories come from? (Anti-)Social media.

I have just had a good look at Digital Spy and conclude that it is not an appropriate forum for technical reception issues, it is a general discussion forum and not specificly aimed at helping viewers or listeners having reception difficulties. This website, ukfree.tv, is aimed at helping with such problems using contributions from several knowledgeable contributors, many of whom work or have worked in the industry.
As is not uncommon, some people think it 'fun' to despoil web pages and sometimes the content of their comments is totally inappropriate, as in this case. I'm sure Briantist will remove it soon as has happened with previous 'spoilers'.
So please allow this website to continue assisting those seeking help with reception problems.

It partly depends on where you live. Not all of the over 1000 transmitters provide a full HD service as yet, so if you local source is not tranmitting HD services, or a limited range of them, you will not get all of them as yet.
As far as equipment is concerned, you need a TV, or set top box (STB), that is labelled 'Freeview HD'. Any that are labelled 'HD Ready' are not able to receive the HD transmissions at all, they can merely display HD input from an external source such as a Freeview HD STB.
So if your local transmitter provides the HD services AND your TV equipoment has the necessary DVB-T2 tuner, as all Freeview HD equipment does, then you should get HD services.
It also depends on getting enough signal strength but not too much. The ideal level for HD is between 60% and 85%. Any less will be unreliable and any more can cause loss of some HD services.

Llandrindod Wells is a Freeview Lite transmitter so only carries the PSB channels. The commercial broadcasters require a sufficiently large potential audience to cover their costs from advertising before they will invest in any new transmission services.

If you provide a full post code that will bring up a series of links that will show which transmitters are receiveable at your specific location. From the one shown as 'digitaluk trade' you can see which are available and what regions they cover as well as how likely they are to be reliably received.

It all depends on where you live, so please provide a full post code so we can see what the reception condistions are like where you are and whether there are any other possible sources that might work for you.
It is unlikely that there will be any more channels available from the Nottingham transmitter, it's a commercial descision by the non-`PSB broadcasters - if there are not enough viewers served then they don't pay to provide their services.
