In the UK television transmissions are usually referred to by a channel number (not. BBC1) as opposed to a frequency. Both. the channel number and the frequency are given on all our Channel Allocation Guides. Since most tuners use channel numbers this 3. MHz difference is not usually significant. Some digital MUXES are transmitted with a channel offsetand these are + or - 0.

Another Amazing New Product: Portable Domes, high spec - fully auto - twin lnb - autoskew - similar to picture left, comes with a decent sized internal dish like the. Direct-To-Home can either refer to the communications satellites themselves that deliver service or the actual television service. Most satellite television customers.

MHz. The vast majority of digital TVs or STBs can still tune in to a MUX even if it has. But if you have trouble. MUXES its always worth checking that the tuner is not being. Finally install the pole on the bracket. The aerial and cable would usually be. If it`s a cranked pole ensure the aerial is pointing in approximately. With the lash wire already.

Eye bolt and the J bolt in the relevant holes on the bracket then attach. J bolt as described above (at 3 above). Further points. Do not install a chimney bracket on the top two or three courses of bricks. Never fit a wall bracket on a chimney, unless it`s a big stack and a small aerial.

If the chimney is ever used, or likely to be used, install the aerial on the upwind. S or SW) side of the stack preferably with.

If possible fit an end mounting aerial (e. This is to avoid smoke damage to the aerial. Installing A Chimney Lash Kit 1 Install the J bolt and the Eye bolt (c/w its attached lashing wire) in the relevant. It is very important to ensure the nuts are unscrewed. Spartan Wars Empire Of Honor Hacks. Straighten the wire out and and slightly. Finally wrap the wire about six times tightly. Now . This is perfectly acceptable, and Is actually stronger than using one larger bracket.

Note the top lash is hand twisted and the bottom one is pre terminated. Also note that the bottom bracket is galvanised and the top one only painted. We only stock galvanised brackets... Health & Safety Disclaimer : Gravity plus height is a bad combination, don`t fall off the roof.

If in any doubt about this scientific fact, don`t do the job. Back to the top. Basic Ladder Safety. This is not meant to be an exhaustive article on the use of ladders, it`s just a.

Surface : The ground on which the ladder is to be rested should be firm, and not. I`d have thought both of these went without saying, but then again.....

Level the ladder : Use of a ladder leveller is the best idea, but not everyone has. Never use wooden wedges or a stone. Place a large piece of plywood. Chock the board. so it levels the ladder but, just as importantly, it`s stable and isn`t going to. Angle of the ladder : This should be about 7.

Some ladders have a . This isn`t one of ours, you can. Back to the top. Note. I`ve seen lashes only wrapped once round the J bolt which haven`t.

Personally I would never recommend a single wrap, but it just. For the above system we would recommend our variable gain mast head amp, in order. Ideally a meter should be used, and not a . But at the end of the day what actually counts is how often the picture/sound. Utilising a 1. 2/1. B tap, and allowing a 2d. B cable loss from the tap to the 8 way.

B to all the above readings to get the figures relative to the signal at the. If the pre amp was used with the power amp  then the total would be 4. B. But it could save your life, or at least ensure you don`t end. If it`s done properly it not only makes using. Instead. of flexing and wobbling as you climb it the ladder will stay rock steady, like going. I mean. And if you do over balance. The best way to tie off a ladder is with one of those small ratchet straps used for.

It`ll only leave a small hole when you remove. Loop the. strap round a rung about half way up, then angle it downwards about 4. Do not. put too much force on the strap because that`ll just damage the ladder. All you want. to do is take up any play in the ladder and ensure it doesn`t move.

If using a ladder in conjunction with a roof ladder always lash the two together. Apart from ensuring the ladder doesn`t. The thing is don`t reach. Top of the ladder : This should be above the top of the wall, by a couple or three. To be honest it`s very rare for aerial installers to ever fall off the roof, though.

Just so long as you`re careful it`s pretty safe fitting the odd aerial. Compare it to driving (over the years you do it), now that is dangerous... Back to the top. System Work. I am not expert in electrical or building regulations, but the last I heard the definition.

That is to say if all. TV distribution systems for earth bonding requirements, as far as I`m aware. The most important requirement for system work is that it must be electrically bonded. All our splitters (except. Co. Ax one), taps and mains amps (except the 2 way amp) have earth bonding terminals. The connection can. Incidentally, use of copper/copper.

RG6  type) is preferable for earth bonded systems. I have to say that speaking as a TV engineer. TV engineer) I cannot actually imagine how a TV, or an.

Could. those only seeking informationplease just find the answer somewhere on this site. Back to the top. Further comment on regulations came from Mike Felton who, after reading our tests. Co. Ax next to mains cable, took the trouble to inform. Electrical Regulations to run 2 different categories of cable. We`re grateful to him for taking.

We`ve been told now, and, although I`m no electrician, it does actually sound like. Electrical Regulations. However, just like the. TV, I have to say I cannot personally think of any realistic. Co. Ax. Certainly not from the electric shock point of view anyway. If one or other of the cables was to catch fire that would be a different kettle.

I`d have thought any. TV lead would be the least of your worries..... That said, particularly if you`re not doing the job in your own home, cover your.

Why does my aerial read short ? Well that really is a question. Firstly not all aerials read short circuit across the input, half an hour with a. Well that`s the wrong question in a way because the dipole(s) are just . Whether the dipole(s) is short circuit or.

Having said that the information in the accompanying. Whilst we`re on the subject... RF isn`t a DC voltage*, it`s AC, and it`s not just AC but very high frequency AC. When. measuring the dipoles I used a standard multimeter set on Ohms, but I also tried. Hz ESR . I was checking the impedance.

That is to say VHF. UHF. The signal can be split to feed more than one set top box by using a splitter capable. F conn splitters will work for that.
