Rewire skyscan antenna?

Postby Southwales » Sat Jan 20, 2018 9:30 pm

Hi, If I was to buy a pre wired scanner antenna like the one below, would it be an easy job to rewire with a longer length of coax so that I could put the antenna in my attic but avoid having joins or using patch leads, if it could be rewired is it likely to be a soldering job, if so just wondering could I make a reliable connection with pf100 coax cable.

It would be a soldering job & you would need much better coax than the rubbish they put on it. The short length of rubbish coax is just about acceptable at UHF. But you would need to upgrade the coax & given the lossy cox fitted I would not recommend adding a second length.
If the antenna as supplied is not suitable, then I would strongly recommend getting a better antenna & some decent Coax. It will cost no more & be a better set up.

Thank you for the reply, is pf100 not suitable?, is there an antenna you would recommend for around £30.

I assume you mean WF-100. That would be fine, the only issue you may have is fitting a BNC too it.
Satellite coax is 75 Ohms not 50 Ohms, but that makes little difference.

Just to add. I believe that WF-100 has an outer diameter of 5mm while RG-8x has a outer of a fraction over 6mm. I am sure someone will correct me, if I am wrong, but as BNC plugs are made for Amateur sized coax, that just means sometimes we need to get creative when using non standard coax & fitting plugs. I use a good quality insulating tape.

I use 75ohm bnc crimp connectors (designed for RG59 cctv cable ) on rg8x cable but the inner core has to be trimmed to fit into the centre pin or the centre pin drilled out to accept the centre core . Any miss match due to the impedance of the connector will have very little effect for reception purposes . An alternative is to use Ftype to BNC adapters again very little loss due to the extra component will be noticed

Hi, Have ordered several f connectors and bnc adapters, have also ordered these adapters so i can also connect my baofeng that I also use as a scanner https://www.ebay.co.uk/itm/2X-F-Female- ... 2749.l2649
