Low Pass Filter circuit?
Posted: Friday 29th Jan 2010, 11:31
Hi guys,
I'm looking to build a LP filter, to prevent my CB signal from splattering the neighbours, when I fire my set up this weekend.
Now, I realise these filters are essentially Pi-filters, but I've been all over the Internet and can't find a circuit diagram or any sort of formulae for calculating the components of the Pi-network.
At one time, you used to be able to BUY these filters, however with "electronics" stores the way they are these days, you're lucky if you can find PL-259 connectors.
Can anyone please help?
Thanks,
Mike.
