|AP510 with original short antenna|
and telescopic antenna
I have fitted mine with a 16-45 cm telescopic antenna and even when attached to one of the rear headrests in my sedan, the 1 Watt of output power tracks very well.
The map below shows a drive from Telemark, about 100 km west of Oslo, to Oslo with as good coverage as one can expect given the valleys and the availability of APRS digipeaters especially in the western part.
|Note the missing tracks east of LA5PPA-1 which are due to a 3.5 km long tunnel,|
Strømsåstunnelen, between Drammen and Mjøndalen.
