First setup VHF 118-160 MHz

Post by NeilP » Thu Apr 05, 2018 6:36 am

Ok,
Not even bought the SDR box yet, but my listening requirements are pretty limited.

Just looking for monitoring of a few Air band frequencies, 119-136 MHz from local airport, 9 miles away and the local marine traffic in the 156-160. Harbour is maybe 5 miles away and I live on the coast ( Jersey, SE Corner) 12 miles or so from France.

So I have my old 2m ham collinear antenna on the floor in the attic. Been there for more than 20 years since I last operated the 2m station (Yaesu FT290)

Just plug that in to the RSP and good to go right ?
The antenna designed for 144Mhz, so should be good to go as it is right ?

Going to need adapter from the big 15mm diameter co-ax down to something for those tiny connectors on the RSP..... what are they called again ? SMC ?


Any thoughts ?
Will this be acceptable?

Many thanks

I would certainly give that a try to start with... If you are 9 miles from where you want to receive, you should have no issues at all, assuming the feedline and antenna are still functioning. Polarization might be an issue.

The RSP's use SMA antenna connectors. If your antenna cable is big & heavy, I'd recommend an adaptor lead rather than a rigid block adaptor. This will take the strain off the system. There's a company called Sinequanon that do ready-made leads and their prices are reasonable. I don't know whether they do one that would suit you.

Be prepared to root about in the various catagories as they have stuff all over the place.

Thanks for the link

Polarization won't be an issue once I get it out of the attic and make it vertical again. ;)


OK, so one issue sorted. Now just need to work out what to do/buy to get a system working

Thanks
