BBC programs on 106 & 107 (HD) & others on COM7 are unavailable in parts of Southampton & Chandlers Ford since the change over. I have had a new aerial fitted by Freeview but no change. The broadcast power is just not enough. Why should we loose our TV just for the sake of 5G phones? When is it going to be rectified?
Can a TV be connected to Freeview and FreeSat at the same time?

Depends on the TV. If it has both a Freeview UHF tuner and a separate satellite tuner then it can. My main TV has both tuners and is set to allow use of Freeview and Freesat. Note that you will need a satellite dish configured to receive the signals from the 28.2/28,5 degrees East satellite orbital position. It must *not* have an LNB designed for use with Sky Q as that does not receive the Freesat signals.
If you already have Sky (but not Sky Q) then if the LNB has at least three outputs you can use one to connect to the TV's satellite input (a screw type called and 'F' connector).

Sorry, I'm not convinced.
I have a 6db attenuator which I have put inline with the TV aerial in order to test out your point. That is enough to drop the reported signal strength on channel 21 (PSB3) from 96% to 92% (but still a reported 0 BER). On the other hand, COM7 (ch55) and COM8 (ch56) are behaving themselves this afternoon and without the attenuator are reporting 90% signal strength with a BER of around 500.
As soon as I put in the attenuator, channels 55 and 56 are completely trashed. Signal strength zero and 2000 BER - and this while PSB3 reports only a 4% drop.
I can only conclude that the reporting of 96% on a high power mux is not the same as 90% on a low power mux and reducing the signal strength is not going to help matters. Perhaps swinging the aerial round to point to Hannington might improve matters - but then there are trees and a hill in the way.

Then you need to get a local aerial contractor in to look at your aerial system. They will have local knowledge that is not available to us contributors who are remote from your location (I'm in West Wiltshire).

I live to the east of Southampton and have an aerial engineer attending to sort out my issues on behalf of Freeview on 9/6. My signal is already marginal so I'm intending to ask them to fit a group E aerial to suppliment my group A and use a diplexer. I dont want to compromise on a wide band as I believe it will not pull in as good a signal as I get now for the group A channels.
This web page explains the procedure if anyone is interested.

I will report back how it goes....

Although I am in a notionally good area, I have a huge tree between the house and the transmitter. Also my house doesn't have a chimney so height is also an issue.
As well as a couple of tvs, I also use an item called an HDHomerun network tuner which enables tv via ethernet. This item requires a high quality signal, more than the stand alone tvs.

I just thought to share my challenges with the retune of COM 7 & 8 to channels 55 & 56.
I was quite happy with my Group A loft aerial receiving all muxes until the retune when I lost both COM 7 & 8.
I purchased a Vision log 36 aerial and installed this along with a new cabling run, but still did not receive COM 7 & 8. I contacted Freeview who sent an engineer who visited and confirmed there was not enough signal strength making it into my loft to receive the signals. All they are authorised to do is swap the aerial for a log36 and anything else like repositioning or moving the aerial outside you have to pay an aerial installer to undertake.
While he was in the loft I asked him to see if there was any particular location which was receiving a less weak signal for 55 & 56 than elsewhere. He moved his aerial about a few positions while connected to his signal meter (half-heartedly I must admit), but we found a slightly stronger signal coming through the side wall of the house rather than through the tiles. After he had left I re-positioned my aerial to point through the sidewall of the house and have restored signal on both muxes, albeit at only 10% signal strength, but with 100% signal quality. The lesson for me on these low power muxes and a loft aerial is that very subtle changes to the position and the direction of the aerial can make all the difference.

I've just installed a group t 20 element antenna to replace my group a antenna.
It has now allowed me to now see channels 55 and 56, however the signal is blocky.
Will upgrading to a high gain "typhoon" bring the channels back?
The antenna is perfectly aligned, i can visually see rowridge from my roof, it has LOS.

I live in Broadstone, Poole Dorset . My post code is BH18 8EX
At present I receive signal from the Parkstone transmitter, which does not transmit Freeview Stations I am interested in. Will I be able to receive Freeview transmissions from the Rowridge transmitter?
