New TV Tuner from HQ

[gordon77]

Some good ideas for alternatives there. Thanks!

For a neat solution (acceptable to SHMBO) I was thinking of mounting a Pi+TVhat in an old set-top Freeview tuner box (available at all good car-boots for a quid or two). But the Belling-Lee sockets on those are usually either PCB-mounted or fixed to a UHF tuner module - not much use.

Something like this any use?

Thanks, Gordon. Good, but no cigar!

I've seen similar, but .... the Belling-Lee/coax socket is not panel-mounted.

For those who are having to edit their local transmitter info, there is an updated set of dtv scan files from the end of September at https://git.linuxtv.org/dtv-scan-tables.git/log/, so that should deal with all the recent retunes. All the data appears to have been pulled from www.digitaluk.co.uk so should be reliable.

I am sure it could be modified if required.

Don't know what they've done but, from having only break-up, I'm now seeing over 100 DVB-T and over 30 radio channels when I did an auto-tune on my TV, all with 'good signal level'. Not bad for an aerial which is hanging over the eves and pointing at the ground. I have an old USB tuner working with tvheadend but as nothing I have supports HD I might be back in the market for the Pi TV Tuner.

This new dongle comes with an extendable antenna (120-350mm) with a 1 metre cable and MCX connector that plugs into the side of the USB dongle. The antenna works best when its length is a multiple of a quarter of the ADS-B transmission wavelength, which is 69mm. Experiment with different antenna lengths to find the optimum.

To get 1 quarter wave (68mm) you will have to cut it.
2 quarter waves (136mm) is unlikely to work well as it will present a high impedance at the bottom.
3 quarter waves (204) will probably work best.

Sir, I was wondering how well an antenna with longer then a wave length would fare? For example an antenna at 408mm which 1 and 1/2
wavelengths or an antenna at 1 and 3/4 wavelength. If your planning on replying to me, it might be best to post it here to prevent cluttering this post
