Diamond D-707 Repair

Ever since I could try out active antennas, I have become a great fan of them. Well, some of them.

For VHF/UHF I used to use a Diamond D-707 omni-directional antenna. It is specified to work from 500kHz to 1500MHz. To be honest - for long, medium and shortwave I have something better, but for VHF/UHF this antenna is excellent when you have little space and want to cover as much as you can with one antenna. The amp is said to have 20dB gain, the gain is adjustable by means of a supply voltage regulator.

But as things go, somewhen the D-707 broke, the amplifier didn't amplify anymore. I assume it was either a close by lightning strike or myself transmitting with too much power in too little distance :(

That was a pity because Diamond has stopped production of this antenna somewhen in the year 200x, for unknown reasons. I did not throw away my antennas (I had two of them), with the idea of repairing them somewhen. Somewhen is now, 2015.
