    I must admit I dont like the screw fit terminals.... as they dont always make good connection further down the track (more subject to corrosion and signal loss)..... but if you get good ones (read more expensive!!) then they probably are OK.....
    Yeah, probably not the Rolls Royce option but if you get decent quality components, and they arent that much more expensive to buy than the el-cheapos in reality, its quite a viable option. And with the judicious application of a good quality industrial sealant they do stand the test of time. Anyway, it doesnt matter which termination method you use, soldering/screw/crimp etc, if there is vibration or cyclic movement to contend with, then the entire end termination needs to be appropriately fixed so as to avoid ultimate connection failure.

    Anyhow Remy, you sound like youve got both knowledge and experience to make a pretty good job of it so all power to you girl.... 8-) Take all the necessary safety precautions wont you :-?.

      Sure will,. last thing I need is to be running around after my family while Im maimed. First thing,.........while my preference would be to do the aerial while the rest of the family are at school or work,.. I will take precaution and wait til hubby is home...just in case I hit the deck. There is no real secure place to tie a rope harness unfortunately, and in case youre wondering why I will be doing it and not traditionally the hubby,lol... it comes down to this; Im fitter, 14yrs younger, light/nimble, have loads more patience, maintenance ability/knowhow, love this kinda stuff and will make less mess on the concrete if I fall *snort*

          Oh sorry REMY Ive only just noticed this post. :-[
          When I was an electrician (practising), I used to do a lot of antenna installs. We used what is known as RG-6 Quad shield Coaxial cable as it had (as the name suggests) 4 layers of shielding as opposed to the one or two layers in regular. We used the F-Type connectors (the ones that have a central pin, usually the coax conductor itself, with the threaded gland) which are far superior as far as reliability and longevity goes. Obviously the number of outlets and the length of the runs is something to think about as far as boosters etc are concerned. Its handy to run all the runs to a central position, say near the manhole for easy access.

            Oh and if youre going on the roof, nothing beats a pair of Dunlop Volleys - dont know how they go on metal roofs though, hmm

              Going up in the roof in about 1/2hour to check out the cabling there already. Just waiting for the ladder the stop dripping :... just brought it in from out in the pouring rain.
              I might need to check three seperate roof cavities,.. but hoping Ill find what I need in the first big cavity,. or at least in the second smaller one closer to the aerial itself. Will take the camera up with me and see if I can get pics of the type of cable and splitter if I can find one.

              Its still pouring rain here...grrrrr..so wont be able to fix the aerial today darn it...typical..hasnt rained here for weeks and just when I need a dry day, it wont stop raining. Its driving me nuts, especially now that I have the HD DVB-T receiver and the potential is there for me to view all channels (& watch entire programs without Remote Man taking control of viewing : ),. while Im working on the computer.......Im only a mere foot in height and a 45deg turn away from happiness. ;D Young son has a pair of volleys that I can fit into,. and I have some pretty good rubber sole runners,. will choose the best grip from those. Looking at it,. I think Ill have to walk up a beam on the edge of the shadecloth (hope theres no wood rot hee hee),.. might give better grip,..tho if the roof is warm, then the iron will would probably be fine,..will just see when the time comes.

                    too true.. the stuff on TV these days is cwaaaaaaaaaaaap.... anything half decent is few and far between.  However  ....this is one of the reasons why I suddenly give a hoot about the reception in this house .  Believe me,..there is method in my madness,.. I have spent the last 10years not being able to watch TV in this house due to Remote Mans powerful force,...a force so great where he is able to block out other family members viewing status and change channels with such speed and dexterity it would make even the most patient persons blood boil.

                    Why Remote Man is so powerful,.. he even continues to control the remote while nanna napping on the lounge every afternoon, and regains consciousness with any attempt to release the remote from his mighty grip,..or any attempt to override his control by changing channels or reducing volume on the TV,..and in a split second, takes full control once again.

                    Why his vice-like grip is so strong,.. he was once painfully woken from a deep nanna nap by a remote melting in his white knuckled fist, and only a mild growl and the remote dropping to the ground were the obvious signs of his agony (true story,..the remote melted).  

                    Remote Man is so unrelenting in his power over the TV,.. the remote often mysteriously vanishes when he leaves the room, and in time,. the remote reappears in wierd places like the backyard, bathroom, bedroom, kitchen, pantry, garage and car.

                    I gave up trying to watch TV long ago and my computer became my source of brain numbing entertainment. But alas there is now hope for me....with my recent purchase of the HD DVB-T receiver for my computer,..  I have controllllllllllllll of my TV viewing at last... I have been freeed from the power of Remote Man ,...and better still..because Im out and about many times a night picking up kids,.. I can record anything I like with the click of a button and watch it when I get back,...without 10mins of ads every 5 mins  .  

                    Yes quality TV programs are few and far between these days,.. but at least now I will get to watch them,.. and in the ultimately preferred way too..while surfin the net at the same time (I could never sit and just watch TV without doing anything else)....if only I can get the darn reception better so that I can tune in all the channels properly with my HD DVB-T.  Reception never bothered me before cos I never got to watch it whaahaahaaha,...poor "Remote Man.  ;D

                      Ok,.. found the splitterssss.

                      A 4way splitter,.. and onto a 2way splitter.  :-? You can see Out2 goes to the 2Way(curl in cable there)
                      [img]www.studioheath.com/images/bits/splitters.jpg[/img]

                      And just wanted to crack the 4way open to see which one was the aerial IN.
                      [img]www.studioheath.com/images/bits/splittergizzards.jpg[/img]

                      Ok,..so from what I can determine,  5 out of the 5 outlets that I thought had aerial hookup, actually are! whoooot! .  

                      I have the 3 more outlets in the kids rooms,... that I want to hook up too. I recall the electrician when we built 10yrs ago, saying he left a bundle of cable from their rooms tied up there (for me to hook up later),.. but no luck in finding it this morning and might need to track him down and ask if he can remember approximately where he stashed it. Itll be under the yellow batts somewhere, and had a look around where I expected it to be,.. but Im not keen to stir that stuff up searching when I dont have an approximate location.

                      Soooooh,.. I will need a splitter (amplified yes?) to cater for 8 cables/outlets. Not sure what quality this cable is (it just says on it, 75[ch937] AIR SPACED COAXIAL CABLE U.V. STABILIZED.,.but it will have to do anyway. Dont think I could be bothered trying to re-cable with better quality or anything and I know 4 rooms would be impossible to re-cable because of the locations of rooms and floor joists over those rooms.

                      So,..next... find the kids cables,.. and buy an amplified splitter(or two?)...still waiting for the rain to stop.

                        Yeah thats just normal RG-6. Thats totally fine. I forgot to mention you might need a power source for the booster. Something Im sure DSE sells, as well as a hex crimper, male f-type connectors, and youll be set!

                          From memory RG-6 Quad shielf also has a 75ohm impediance.

                            Yeha rather than looping from one 4 way to another 2 way, just get yourself an f-type rack splitter with a heap of outputs on it too!

                              Remy,

                              Yep looks pretty good!

                              Id lose the 4 way passive splitters as YeeZa suggests above...

                              They reduce the signal quite a bit..... and when "daisy chained" like yours.... the loss is considerable.....

                              A multi-way amplified splitter (with at least the number of outlets required) is definitely the go....

                              Id say most of your problem is at the pointy end - the antenna. Direction is wrong, it is too low and check for corrosion, spider nests etc in the balun and also corrosion where the balun connects to the aerial terminals.

                                Cool thanks Yeeza,.. writing all this down before I go anywhere near DSE. Might also look online for the parts too beforehand,..it will help me know exactly what Im after (visual learner) and avoid brain fog in the store.

                                Yeah,..thought the loop was a bit slack.. but suppose a 5 way might not have been in the truck ;D. I was thinking of getting an amplified 8way,..but wasnt sure if such a thing existed.. they do... well in the UK at least.... still looking for an OZ site.

                                Ok,.. power source....can do.
