Specialising in high tech amateur radio RF kits, the current
range of DDKits consist of the VLNA or very low noise amplifier
used worldwide for EME and Radio Astronomy. Kits are available for
the 70cm, 23cm, 13cm and 9cm amateur radio bands, and for the 21cm
Radio Astronomy band. The VLNA13 can be used from 2.2GHz. to
2.5GHz and it was a VLNA13 that was used in the successful Bochum
(Germany) VENUS bounce tests a few years ago.
Also available are the wideband PGA amplifiers for use between approximately 30MHz and 2.5GHz, offering low noise, high dynamic range and medium output power. The PGA144 is a contest grade 2m preamplifier featuring 'proper' input filtering to protect against blocking from Band 2 FM transmissions. This preamplifier is equally suitable for contesing and EME. Versions for 70cm and 23cm are coming soon.
Anglian 2 transverter was a great success with hundreds sold. A redesigned Anglian 3 is coming soon. 8, 30 and 60W 2m PA short kits provide the Anglian transverter user with more output, although the Anglian without a PA is suitable for use as a transverter for driving microwave band transverters from your favourite HF rig or SDR.
The full range of WA5VJB PCB antennas are stocked and available with SMA connectors where appropriate. Some of the antennas require the use of a pigtail connection instead of a connector.
