Hi
My caravan Humax 4000T has given a few years service but this trip it is not delivering non pixilated picture or sound.
Quality and signal strength are 80%.
My Viera Panasonic tv tuner gives crisp pictures and perfect sound.
When I hold the rf input cable tightly to the Humax I get an improvement but not as good as its usual clarity.
Must I bin this excellent box?
Most problems like this are caused by poorly fitted belling Lee connectors. These should have the centre core soldered.
Best to use satellite grade cable and f connectors with f to belling lee adaptors.
the confusing things for me are
1 the box shows 80% quality and strength signal-this produces a good picture on the Panasonic Viera tv tuner.
2 I am using a high quality Digisignal cable with Digisignal adapter-the tv tuner is using a much cheaper rf connector from the same caravan aerial.
The rf built in female connector on the Humax box is showing signs of wear and tear.
While the connector appears to be a quality Humax item the core connector has spread I pushed/squashed it together with needle nosed pliers but I fear it is failing to make a good enough connection

Which channels are causing the issues and which transmitter ? It’s possible that changes to the transmitter frequencies have made your aerial unsuitable.
This particulary applies to channels on COM 7 and COM 8. These are being moved to Single Frequency networks (SFNS). You may be located in a area where you can no longer use these MUX.

BBC quality is poor on Humax perfect on Viera TV
STV poor on both
Rumster Forrest transmitter 27 miles line of sight.
I am at postal address KW9 6LP
Using Status 570 antenna system

No idea what a status 570 antenna is.
The equivalent English channels (yours are STV). all look really good on my 5000T.
Have you considered using a smallish dish and a freesat box ? The UK spot beam transponders are now very strong so even a Sky Minidish should work well.
The primary area is within the red line

Have you worked out what caused it to spread?
The antenna is a factory fitted unit to my 3 year old all plastic UK built 3 year old Swift caravan.
In previous years this site was incapable of getting a usable predigital terrestial picture.
I always used a 60cm cheap Sky dish and my Humax twin tuner Freesat box using cheap Sky quad LNB.
Thanks to new satellite I can use a 40cm Sky dish in Thurso and still get a good signal.
I think the Humax rf unit centre connection spread due to the constant plugging and unplugging as the box is set up and dismantled every time I use it on holiday.
Being retired we tend to use the caravan most of the summer-but-not this year.

Doesn’t say if its a wideband design or any other details. How will it cope with Mobile sources in the UHF bands

Make a coax patch cable with a male belling lee on one end and female in the other. Secure the male in the box. Connect and disconnect from the socket on the cable end. If that fails simmply replace the female connector. F connections are much more reliable than the ancient Belling Lee ones.
I agree.
Now moved to Aberfeldy Caravan Park where the nearest transmitter is 4.1 miles away-Grandtully-even worse reception than Brora!
The good news is I am now certain the problem lies not with the Humax box but with poor terrestial reception.
I will get out my Humax Freesat twin tuner tomorrow-if the rain forecast is wrong-or-probably read either Jason Platos How Not to be a Professional Racing Driver or TM Devine The Scottish Clearances.
The only books in the caravan.
Many thanks for the help and support-great forum-great boxes-in my opinion
Now on Fraserburgh esplanade persevering with 4000T freeview.
Tuned to Rosehearty 4.2 miles away using 570 in vertical mode.
Getting 100% strength and 95% quality on tuners 1 and 2 nothing on tuner 3.
My problem is pin sharp picture on live channels but pixilating on recordings.
Is this a case of poor reception-yet again?

You will only get a signal on tuner 3 when tuners 1 & 2 are tied up recording.
tune to channel 1 and press the record button to record BBC1 SD.
tune to channel 3 and press the record button to record ITV – SD
tune to 104 and press the record button to record Channel 4-HD.
Now display the signal diagnostics.
Recordings should be identical to live TV. A recording is a bit for bit exact copy of the live TV stream. You may have a hard drive problem. If you don’t mind losing your existing recordings try a hard disk format.

Many thanks Grahamlthompson-problem solved pin sharp pictures on all 3 tuners having reformated recorded content.
The only puzzling thing is tuner 3 shows nil signal and nil quality but is producing recordings of equal quality as tuners 1 and 2.
