The fibreglass whip plus spring has been replaced by a measured length of scrap zinc plated steel wire and a ferrule from an old analogue mobile whip.

2M antenna 0113

The TV antenna was removed. Faults in its feeder matching were repaired and the antenna placed in the roof space. Above the roof is now fully available for non-bludging antennas. This 2m antenna is constructed from a dexion bracket recovered from a telecoms site ~30 yrs ago, a mobile base even older. The vertical is the screw-on part of an analogue mobile whip and the whip is zinc -plated steel wire found while out walking. The ground plane is galvanised wire from a coathanger. The feeder is an RG59 equivalent from a disposal source.

My 2M antenna at home as first installed. This 2m antenna is constructed from a dexion bracket recovered from a telecoms site ~30 yrs ago, a mobile base even older and a mirror mount clamp. The vertical is the spring and whip I use on vehicles. The ground plane is galvanised wire from a coathanger. The feeder is an RG59 equivalent from a disposal source. In 2013 the fibreglass whip was replaced with suitable length of galvansed wire in a ferrule from an old mobile phone antenna. It was a nuisance having to climb up there when I wanted to work from a car.
