Ok, but say a mast is transmitting at 61dBm, on a spectrum analiser would this (without use of an amp) ever show above 61dB?

jb38: Guess what.

We routed the aerial down straight into the Sony TV. Perfect picture.

Then connected it via the splitter/amp. Broken picture...

New amp and everything is working fine, signal strength indicator on the sony is high.

Not sure why he didn't figure out the amp was the problem first time round, however it all works now, thanks.

Keith: Thanks for your update and pleased to hear that the problem is finally solved, but though as far as the issue concerning the splitter / booster is concerned this "was" the device that had initially came under suspicion as being the reason for your problem, as in my original reply (@ 7.14pm / 29th) to your posting I had queried if this device had been checked out by the aerial installer, you having confirmed in your reply (@ 01.37pm / 30th) that it had been, and adding words to the effect that your own suspicions were also with this device and why you had purchased / then returned another booster which when installed as a replacement had not made any difference to the situation.

Although everything appears to be OK now and I suppose that's all that really matters, but from my point of view (as an engineer) there is still an iffy element about the exact reason for your problem, because "if" the original cable had been OK then the problem was being caused by the booster / splitter, but as the replacement booster / splitter referred to was found not to have made any difference to the situation then the reason for the problem automatically reverted to the cable being faulty, as I would find an aerials coax downlead, as well as the booster / splitter attached to the end of failing at the same time a little too coincidental to be factual, my suspicions being that the aerial installers words vs actual actions are not necessarily running in parallel lines and something had been overlooked that he cared not to mention.

jb38: I wonder if it's possible to damage an amplifier/splitter by e.g. shorting its output. Since at some time it did work, and changing it made no difference (this was about 3 years ago).

Like you I am a bit mystified as to why he didn't identify the problem as being with the splitter. He claimed to me originally that the signal strength was weak but the booster was doing its job. It was after that he decided to move the aerial and made matters worse.

Still it works now and I can go and watch the tennis!

Keith: The only type of aerial amplifier / booster than can be damaged by causing a short circuit across any of their sockets (whether input or output) are the types that provide power to a mast head amplifier, the 5 / 12 volts DC being on the aerial input socket, the power travelling "up" the downlead and into the mast head amplifier located on either the aerial itself, or alternatively a small box mounted on the mast pole.

My personal suspicion is that the problem was purely being caused by the old downlead cable, and if indeed the aerial installer had said what you have reported i.e: signal strength was weak but booster was doing its job, then this is an admission that the booster must have been working because if it wasnt the weak signal would have vanished as there is no in-between states, they either work or they dont!

If the aerial installer left the old booster / splitter with you maybe you could let me know the model number printed on its ID label, as this would enable me to establish whether or not your system uses a mast head amp.

jb38: I ripped open the old amplifier. No real info on it but "Electro-replacement Ltd Model SIG 4". The input is capacitively coupled to a 2 stage transistor amp whose output appears to be inductively coupled to the 4 outputs. No masthead amp.

One point - the 'old download cable' you mention is still in place. I wonder if there was just a faulty connection (he did undo the coax connectors to check them).

Keith: With regards to the old amplifier / splitter, if the rear of its aerial input socket is coupled onto the PCB via a capacitor with no DC bypass circuit in place then this is a positive indication that your system is "not" fitted with a mast head amplifier powered via the splitters aerial input socket.

As far as the reason for the problem is concerned, I do have to admit that when I referred to you having purchased then returned another booster splitter I was not aware that you were referring to 3 years ago, me having assumed that this had been done prior to making your initial posting, but though if the aerial installer you called in "since" making your recent posting had given the OK to the booster then it had to be the cable / or connections at fault.

But though the fact still remains that if the aerial installer had followed standard fault finding procedures then the reason
for your problem should really have been diagnosed within the first 15 minutes of his arrival, that is "if" on arrival he was kitted out with a proper signal meter thus removing the element of guesswork from the equation.

By the way the only device I know listed as " SIG 4" is made by the company in the undermentioned link, this device having 16dB gain on each of its outputs.

PS: With regards to zero signal until the booster / splitter was changed, pity you ripped it apart because I would have liked you to have tested it out, as I still find it strange for it to be OK on the first visit then suddenly be defective on the next, although I would prefer to keep my ideas about that to myself.

jb38: On his first visit, the aerial man definitely tested the signal with some handheld instrument - I did not get a good look at it but it showed several vertical bars on a LCD screen. He told me that the signal strength was weak at the TV, weak at the output of the booster, weaker at the input of the booster and then got his ladder out to measure it at the aerial itself. It was then he claimed it was weak there and the aerial needed repositioning. After that he told me the signal strength was 'good' at the TV, although it could not get any picture! This was when he claimed the TV might be at fault...

Something doesn't add up but I guess I'll never know what, unless the problem reappears.

Keith: Thanks for the latest on the issue, however I stick by my previous suspicions with regards to the aerial installer having overlooked the real cause of the problem, but as a face saving measure having covered this up by "arranging" another reason for your difficulty as something does not ring true about what you have been led to believe.

The only thing I will fully agree with the installer about is by his action of moving the aerial, however as your problem has now been rectified I suppose the whole issue to be relegated into the class of being one of those "open verdict" cases as to the exact cause of the problem, albeit I still suspect that the downlead or connections at each end of were really responsible.
