Looking for a powered RF splitter
 

Radio Shack used to sell a powered 4 way RF splitter.
One RF signal in, 4 RF signals out. Supposedly something
like a broad band emitter follower.

The Radio Shack things were junk: noisy, poor high
frequency performance, not as good as a passive
splitter.

Is there anything on the market that does work?

TIA

There's plenty over here in the UK that work perfectly adequately, generally
available from any reasonable electronic / electrical outlet, so I'm sure
there must be over your side of the pond as well. Bear in mind that with
terrestrial broadcasts going digital all over the world, if the transmission
system that your broadcasting authorities are (going to be) using, is
anything like ours, then any kind of distribution amplifier that you use
needs to be specced for the digital signals, which over here means very
wideband, and very linear. In my experience, the digital signals are
actually nothing like as robust as they would have you believe ...

I had the RS amplifier in at the old house. Seemed to work fine, had
adj. gain. It was the one that also allowed internet to pass through
without amplification. The cable guy explained why it was not good, but I
forgot the reason. I have tried a few, and made my own. All tend to be
problematic.

In the London area, FreeView digital is within the grouping of the
analogue channels so no alteration is necessary. The ERP of the digital
transmissions will be increased when analogue ones cease.

I'm sure I read somewhere that they now say that the power won't be
increased, as that would 'cause interference' to equipment using
channels they propose to sell off!

I agree with you. Woolworths do one, but its only two outputs and does
indicate its suitability for digital. Bit expensive though at £12.00.

Could be - but it would require a major re-vamp of the proposed final
network - more fill in TX required.

Just had a look in the horses mouth and nothing about any changes there.
It's the 'Existing 81-Site Plan' pdf.

Have you ever been to bingo ? Sadly, I have to admit that I do attend my
local club (just to keep the wife company, you understand, although I do win
quite a bit of money ... ) and the caller there does occasionally call 11 as
"both (or all) the ones, onety one !" just for a laugh. So sometimes, it is
!
