Default ant

I run a Maco V5000. It does a very good job. I have run a Imax 2000 & it works good. The V5000 can stand all you can put into it, but it can not stand a direct hit from lighting. jim

i just noticed this is in jays section .........
have you considered a interceptor 10k ? they are pricey but supposed to be very very durable . it should perform as well as any other properly designed 5/8 .
or you can home-brew something yourself that suits your wants and needs .

Commercial broadcast antennas take direct hits on a regular basis. Most of the time no one even notices because they are designed to sink the currents involved directly to ground. Sometimes the transmitter fails, the antenna can have holes punched through it and loss of pressurization. Other times the center pin in the flange connector opens up and you lose the bay.

ALMOST TRUE ......

However even the commercial ones we use here get smoked ........

On 460mhz we use 4 and 8 bay diploes and we do lose them this is why we keep extras in the repeater room .....

These is a difference between the antennas used for two way radio and the commercial broadcast versions I'm talking about. These antennas are often constructed from heavy wall brass tubing over 3 inches in diameter. It's a little harder to smoke one of these but as I said they still get holes punched through them and the center pins of the 1-5/8 inch EIA connectors can burn right open on some strikes.

A 3 inch dia antenna at 460 mhz ?

Ours are DP folded dipoles and some 6DB gain ones in fiberglass domes ....
No Comet or Diamond junk no ringo rangers and no MFJ's

We still lose them once and a while
