No, wide beamwidth with lower gain. Lok up bowtie arrays for clues on how to deal with reflections. As I said, once the (absolute) signal is over threshold it is less important, provided the noise level is OK as it normally would be. No point having 45dB of signal and a 30dB noise floor! That...
Many TVs have a crude BER reading in the settings. You will find signal strength and "quality", so tune for maximum 'smoke' but be less concerned about the signal strength if adequate. Also avoid internal installations and cheap cable, then with the improvements that have been made in error...
Bit Error Rate, in effect the "quality" of the signal. It is a measurement of the amount of error correcting that is taking place.
Once over threshold, signal strength is irrelevant and so you tune for minimum BER. Indoor installations feature frequency dependant reflections which causes havoc...
This the information I was given by a qualified electrician doing the testing. He was not touting for work because he knows I will do it myself. I am not sufficiently au fait with the latest regulations to argue the point.
The first thing to understand is that internal aerials are not suitable for digital services, regardless of price, quality or design. Even a 10 element externally will be far superior to anything in a roof space.
(a) HMOs meeting the standard test
A building meets the standard test if it is a building in which more than one household has living accommodation (other than self-contained flats) and:
at least 2 households share a basic amenity, or
the living accommodation is lacking in a basic amenity...
Because I have just had the obligatory electrical testing on the main premises and when he looked into my private workshop's DB, that was his verdict (even though the workshop was all locked up and the lights were out, so therefore nothing in there could be seen nor tested.). :whistle:
I want to improve the protection in my workshop which is for my private use only. DB is an old MEM Memshield and I was hoping to just fit an RCD to, at minimal cost. However it seems that the correct device is hundreds of pounds, which is not going to happen.
In the absence of other...
