Use a spliter and not a T, so do not lose signal.

Johnn,

You will lose some signal if you connect two devices to the same antenna.

Martin Lynch has the following item or check web.

The SP – 3 (RF Systems) splitter makes it possible to connect two receivers simultaneously to one wideband- or VHF-UHF output of an indoorunit. Both receivers operate if they are connected to their own antenna.

The high isolation of this splitter assures that both receivers are completely separated: there is no mutual influence such as signal loss or birdies generated from one receiver into the other. The frequency range of the SP – 3 covers 10 MHz – 2500 MHz.

This will stop any interaction between the two receivers and keep loss as low as possible.

There will be some signal loss but thats price you have to pay.

Good quality coax and connectors must be use at all times.

Regards

If anybody is interested in a SP3 Splitter, I have a secondhand one for sale.

Am I right in thinking with a splitter I could have radarbox and a scanner off of one antenna? ( Both of which work off the same antenna well)
Thanks

I don't think the RadarBox antenna is designed for use with a scanner so it could be academic.

I dont think it would be a good idea to use the one antenna for both radarbox and radio.  Radarbox is better using one dedicated to 1090Mhz and radio 108-136Mhz.

I think Alan has summed it up better than I did, that's what I meant to say
