Hardy,
I alternatively use an Alfa dongle. It has more oomph than the Edimax, but can only be used on the pc, connected, unlike Edimax it does not transmit to phones/tablets.

that biquad, something wrong, space between dipole and reflector usually 15mm, not 30.

You can find designs for wifi antennas online . I agree that swr is more important for wifi as it transmits .
The biquad I linked to was calculated for 50 ohms . Maybe the 30mm is the calculated value . The lower figure gives more gain . Perhaps they usually accept a worse SWR than optimum.

I have made your biquad, and a similar one for 5ghz. The design is wider and shallower than others but works better, though not as well as my yagi.

Woodbridge
I've just moved to Woodbridge (IP12 4DD) and currently don't have a TV aerial. I'm intending to attach the TV aerial to the chimney stack. I presume that I should align to the Sudbury transmitter even though a repeater transmitter exists in Woodbridge. The aerial group for Sudbury (and therefore I presume Woodbridge) in 2020 therefore do I need a K group aerial now, in anticipation of the change in 2020 ?
Can you advise; best aerial to buy, best transmitter to align to.
Many thanks,
Paul

Paul Dicken: According to the DigitalUK trade checker for your postcode, Sudbury should give good coverage. The Woodbridge relay is predicted to be poor. You would be best off installing a wideband type aerial, such as a log periodic design which will be suitable for receiving all current frequencies and able to cope with any future frequency changes.

Paul Dicken: Frequencies changed at Sudbury earlier this year, and I can't see anything else planned, certainly not in 2020 : I am also on the Sudbury transmitter here in Ipswich. What did you think was going to change in 2020? (just in case I've missed something)

Dale Rumbold:
There are changes shown as planned for April-June 2019. Though the channels used are not planned to change, other aspects may well. So StevensOnln1's advice to use a wideband aerial is correct and suitable for all predictable future transmissions.
It is worth noting that there are plans to change the encoding of most signals from DVB-T to DVB-T2 over time so that more HD services can be provided. That will also allow more channels on existing transmitters. It cannot be done 'all at once' as people will need to have a TV set, etc that is Freeview HD capable.

you mean we will keep the existing channels but some will become HD? Why oh why can they not leave things alone now? This will make most of my freeview boxes useless!
