Original version - made in USA

A replacement top section for the Solarcon A99 base antenna.

Limited stock available of the original Firestik A99 upgrade. Made in USA.

Not only is this shorter than the original A99 top section, but also claims a higher gain because it is wound (like a Firestik) rather than just a straight wire.

Length 155cm.

Everyone who has used one has reported some gain over the standard A99.

Not only is this shorter than the original A99 top section, but also claims a higher gain because it is wound (like a Firestik) rather than just a straight wire.

Length: 157cm.

Everyone who has used one has reported some gain over the standard A99.

Loft Ground Plane Kit

A groundplane kit to allow you to use a mobile antenna in your loft etc.

Consists of a small aluminium plate (approx 6" square) with a hole in the middle to accept a standard antenna mount. Attached to this are 4 aluminium groundplanes approx 1.5m long, which lie flat on the ground.

Not ideal, but with a reasonable mobile antenna this will work better than any of the "loft" antennas.
