Until you get an attic one set up if you are looking for something low key and cheap try one of the wide range whips you can get and put it on your gutter. It may even do better there than a bigger one inside your attic.

Something like this https://www.maplin.co.uk/p/miniscan-mob ... enna-qt30h but as maplins go that is a bit expensive. Loads of similar ones on ebay around the tenner price mark :mrcool:

Hi, Where is the best place to but the none stranded heavy duty wire, also is that plumbing pipe that you have used for the centre tube? Which coax did you use, should I avoid rg58? Thank you for your help?

I have one just like that one coming from from China for £3 https://www.gearbest.com/Bnc-Antenna-_gear/ could I just extend the cable with say rg58?

Also what about these skyscan antennas or are they more of a gimmick https://www.ebay.co.uk/itm/SKYSCAN-MOBI ... SwGtRX1~nj

AsI have said previously RG58 is not suitable for UHF and would not recommend its use for frequencies above 30Mhz

Coming to amateur radio from a past of pirate broadcasting & QSO operation on Shortwave & below, I set my first dual band antenna up with cheap RG -58. Sitting in the garden with my handheld radio I could hear stations on the standard duck on 70Cm than I could not hear upstairs using a decent high gain dual band antenna & 10 meters of RG-58.
Height is important, very important, but despite a good 12 to 14 meters of extra height, plus that improved antenna, I was still worse off than with some tiny antenna at ground level.
The RG-58 was some cheap CB rubbish I had brought from a local CB shop & I am sure decent quality RG-58 would have performed better, but even so, RG-58 as Chris said is of no use at UHF.

Is there anything out of these coax cables you would recommend https://www.screwfix.com/c/electrical-l ... t_by=price

I have just ordered 25 metres of rg6 for £1.39 @ screwfix, cheaper than rope. At that price I hope it is worth it just why I experiment with a few home made aerials. https://www.screwfix.com/p/labgear-rg6- ... rown/80767

For receivers - 75Ohm cable is generally OK, and RG6 meant for satellite systems has a pretty good technical spec. The only tricky part is connectors - most ready built antennas have 50Ohm connectors and bodging RG6 into 50Ohm connectors is a fudge. If you're just going to connect using terminal strip or similar not too much trouble - just be careful to support the copper drain or open braid as it's not got huge amounts of copper in it and isn't that strong.

I have now ordered pf100 cable hoping it will be better and less signal loss. https://www.screwfix.com/p/labgear-pf10 ... hite/45490
