Hello i am looking for some help on this new vector 4000 i altered to install a bigger gamma rod and been having corona issues within the tube and not sure how to fix this . Has anyone tried running hi power one of these antennas and got away with it?? Im on my 3rd gamma gamma rod 10k 20k 30k . All in which arch out within the gamma rod and eventually fail.
 

Its a 1kW continuous, 3kW short term rated antenna. More power is pointless. You would have to put 4kW into it just to get a single S point improvement over continuous use.
 
If you are running big power you need to get a better suited antenna that handles a lot of power like a shockwave with a din male or direct feed connection. JMHO. You may be able to mod it but using SO239 and PL259's has to go. The sirio ratings are over inflated a bit in sure as most antennas manf. Do this, but an antenna like the shockwave or Similar antennas are built for power and long term use of it. It's cost more, but you won't be spending a lot of time and maybe some burnt equipment trying to figure out how to prevent this issue from happening on the vector. The Interceptor 10K or 25K antennas, made by Jay in the Mojave, is another antenna that comes to mind. Again not cheap but handles a lot of power. JMHO. The Shockwave antennas are made in the USA as well. Not the Australian ones. Again this is JMHO. There may be a fix for what your issue is, arcing, but Idk or haven't seen anyone speak on the subject of upgrading it to handle more power than its rated for, which again I think is overinflated. Hope you find and answer and have a great day!!
 
Spot on. When you look at those antennas the one thing that is noticeable is the massive spacing between anything in the matching sections compared to the Vector 4000.
