Effective protection for commercial use
|
Time owned: more than 12 months
|
At our commercial HF monitoring and point to point transmission site, we provide services for several commercial and government entities. We get to work ham radio too during off hours.
Some months ago, we replaced our "DC blocked" Polyphaser units with Alpha Delta TT3G50 surge protectors. We did this because several of the Polyphaser units failed during 1000 watt continuous duty transmissions over a 1 to 2 year period. We discovered the capacitors in them failed during high power operation. We asked for the rating specs but received no response.
We tested both types of designs with our high voltage, current limited pulse generators to characterize surge protection performance. We found the Alpha Delta units provided the same nanosecond (approx 80 nsec, as verified by an outside lab) "response time" as the others and the discharge protection is as effective.
The Alpha Delta units have no internal capacitors to break down and the reliability has been flawless. We have changed our systems in the U.S. and Asia to the TT3G50s and have been very satisfied with the performance. The Alpha Delta folks have been very responsive to our questions.
As always, we use commecial grade grounding techniques (single point grounds, etc.) because no protectors can do the job by themselves. We have sustained no equipment damage or failures at this point, and some of our HF antennas are quite large.

Works as expected
|
Time owned: 6 to 12 months
|
I got this little jewel after a particulraly cold, dry and statically electric New England winter. I zapped my radio pretty good, neccessitating a trip to the repair center. Afterwards, I decided to upgrade all my static protection. I got the AlphaDelta ATT3 G50 from Universal Radio and hooked it up. Installation was easy. I haven't noticed any loss in signal strength, and have saved myself much worry when it really gets dry, cold, snowy and windy.
I will change the arc plug before the next winter season to be on the safe side. At 10 bucks, it's a small investment.
