Hi,its been long i last left Radio Amateur after passing my exam.Planning to restart this hobby.

I am planning to get this set:
Transceiver TYT TH-8600
Antenna Diamond X700
Power supply maybe: Diamond GSV1200 or Diamond GSV3000 or Diamond GZV4000
still figuring out on swr+dummy load+antenna tuner

Any advice?

Congratulations! Now people are trying to port over to digital stuff like Yeasu Fusion and DMR. I guess you could skip everything and just jump over on UHF lol
I only keep one Baofeng for VHF use.

Wait, why you need to earth your antenna?

You don't ground the antenna, you may want to ground the antenna mast but, lightning loves the fastest way to reach the ground and your mast probably will attract lightning more than before Get a lightning arrester if you want to protect your equipment. I grounded my mast and I've arrester inline with my feed line. The best protection is always disconnect your equipment when you're not using it. I've a gateway radio running 24x7, and I had hit by lightning before, not direct hit though on my radio but my HF set went kaput along with my TV, and astro decoder. My VHF set seems to be working fine till now, probably the static went into my HF set through power line instead of antenna feed line.
