Just asking question is several sources and then, making an informed decision. It does look that I can get 10dB gain by changing from wide band aerial to the XB10A. I tried looking at Signal strengths on TV but it does not seem to have option to see them.

yes .... 3 separate forums, just getting knowledge to make informed decision, The benefit of forums.

The issue is the Humax box reports signal strength is less than 50% So questioning whether I need to upgrade the aerial.

Put OS grid an 8m height .... advises to use Vertically polarised extra high gain aerial. The aerial is mounted as per pic .... sorry its not too good a picture. Points straight out through tiles to Kilvey Hill, but village is in a bit of a dip hence low signal. This aerial was the one...

I don't see why it contradicts? If I connect Aerial direct to TV, SD programs are OK, but HD programs are a bit flaky. The house is in a poor reception area. Once aerial signal has been through the Labgear amplifier the HD channels have no interference. Yes fully agree an outdoor antenna is...

I currently have a Vision V10-321 installed in my loft 32 Element Wideband Vision V10-321 I am getting my signal from Kilvey Hill (Group A) House is at a marginal reception, SD channels OK, but HD has interference. As I needed distribution, I installed a Labgear LDA2061LR, and HD signals are...

The amp came with a terminator fitted to the 'main' port .. no idea if it's 75ohm or not.

That was what I assumed - Distribution signal is at optimum level. I can't plug lead in direct due to location

I have my incoming aerial feed connected to a LabGear LDA2061 distribution amp. All TVs connected are working, but if I check signal strength - not that high : From Kilvey Hill Transmitter 21 strength 40% 22 40% 24 36% 25 38% 27 42% 28 42% 34 22% Quality states as 100% on all. Should I be...

I often see posts on people selling cutting boards or similar made of glued-up strips of hardwood ... Maple, Acacia, Cherry, Walnut I's like to make a couple of these in a custom size. Anybody know of a good source for such woods, my local timber merchants have loads of structural materials...

I thought of that, but forstner have only cutting face. One I was thinking of have normal flutes like a twist drill, but flat cutting face with a centre Brad point. Nearest I have found is a dowel drill

I need to drill some flat bottom holes in hardwood. (12mm diam) Ones I used previously are a bit like engineering end mill bits. Is there a particular name for these bits …. So I can find one on-line.

A neighbour just donated me 2 VGC twin 6' fittings complete with Phillips 75-85W tubes, While I have the slimline tubes & fittings in my garage, I could utilise these over my workbench. Should I just use as is .... or is there an adapter to use slimline Tri-Phosphor tubes, I can see an adapter...

want to have as thin a 'protection' as possible

Often instrument cases are made of wood , but have a black 'felt' coating over all the compartments to protect the instruments .. Typical (but old) such case in sample pic Is this 'sprayed on' or is it a glued on fabric ? .... need to make a few storage boxes and need to have them lined...

If you don't like my post please feel free to scroll on by, there is no need to be discourteous or insulting this is an open forum. I am not clueless, the sketch is done using what I have to hand, (PowerPoint), I don't have access to an electrical drawing package to produce using IEC 60617...

Others have understood the ask ... apologies if you are not understanding or possibly reading too much into it. The fan is fully controlled by the controller, the output of which is 0 to 12V, and as its variable speed it can be any voltage up to 12V ... I have measured and at full speed it is...

I could not bother with the LM393 comparator … and instead use a simple 741 op amp

Taken suggestions onboard Now it looks like this sketch I know I need to use current limiting resistors for diodes ... not sure if I need any diode protection for relays, normally add an IN4148 across the coil. Existing physical switches are unchanged just now driving relays as per suggestion...

Its DC 0 to 12V
