There is a HUGE difference between the Maco V58 and the 5000.
The V5000 has a larger diameter base insulator. This insulator is supposed to help eliminate any arching that may happen. Unfortunately, they use a small screw to hold the main radiator to the insulator and this screw is close enough to the base tubing to still allow arching. You can remove this screw, but the only thing left holding the main element up is silicone! As stated above, they also run a thicker wire to the ring. The rest of the components are the same.
If you must go cheap, get the V58. You will gain nothing with the V5000.
If you are running big power with a big radio, why not buy a big antenna with big coax? The BEST money you will EVER spend on an radio system is on the ANTENNA and the FEEDLINE!!!!
People are so quick to spend big bucks on an amplifier, but go cheap cheap cheap when it comes to an antenna. It's foolish! I also HIGHLY recommend LMR-400 (or equal) coax!!!!
If your plan is to run 1500 watts or LESS, the V58 will work just fine. If on the other hand you plan to exceed this rating, I
HIGHLY recommend the
Interceptor 10K!!! Again, you will gain NOTHING by running the V5000 over the V58.
For those running stock power, you too will gain a NOTICEABLE increase in performance by running the I-10K!
Just in case I wasn't clear:
The BEST money you will EVER spend on a radio system is on the ANTENNA and the FEEDLINE!
