The first is a small 20cm high simple stick aerial, costing a few pounds. This was found to give adequate reception of (16QAM-mode) Freeview channels in strong signal areas, especially outside.
However, unless it can be placed in direct sight of the transmitter an only unsatisfactory signal can be received.
The second form of aerial is of the Yagi design of around 30cm length, costing around 10.
This aerial was slightly better than the simple stick design, largely because it can be directed to point at the transmitter and be positioned horizontally or vertically as required.
However, in poor signal areas the 64QAM channels were not received, and the aerial required good placement to get an uninterrupted Freeview signal.
Indoor Panel aerial
This was found to have around the same reception quality as the Indoor Yagi type, and cost around the same.
Indoor digital aerial with booster
Costing 25-30, the improvement of the signal provided by a modern internal TV aerial. Typically able to boost the signal by 36dB, this type of aerial when well positioned provided stable, uninterrupted Freeview reception on all channels.
Please can you advise simply what I should do to get back my channel 3 , 4 , 5 etc reception on freeview with my loft mounted aerial. It disappeared just 3 days ago - no previous problems with any channels
I have recently bought a 32 inch Samsung tv which states that it is freeview ready. I connected the old aerial which I used with the old tv (via a set top clarity box). The old aerial which is indoor give good reception on a good range of channels. However I don't get UTV or CH4, or CH5 (note that I do not use the old clarity set top box now). My postcode is BT38 7NJ. I am not quite sure which transmitter my signal comes from as there are Black Mountain, Carmoney, and Whitehead. I am a bit puzzled as I expected the new TV to pick up on all channels. I have retuned it a dozen times but I still don't get these three channels. Is there anything obvious about this. The signal qualitytest reads 100, and the signal test strength reads 95 on a lot of the other freeview channels.
Graham: If the indoor aerial referred to is of the "same room" type, then nothing can really be guaranteed as far as reception is concerned, although loft mounted aerials are generally OK provided that said aerial is not facing into a water tank.
However, the Divistransmitter @ 12 miles away is indicated as being the main station that covers your area, the three channels you report as missing being transmitted on Mux C21 from this station, and so go into your TV's tuning menu and select "manual" tune, entering C21 into the box then pressing search or scan, should the missing channels be received during the manual scan, then they will (or should) be automatically added into the programme guide.
