Welcome! Hope you enjoy the forum and your new Navara. I noticed that it looks like you have your uhf antenna mounted on the base of the bull bar in front of the bar work. I did exactly the same thing but what I didn't take into account was how much the antenna "oscillates" and whips back & forth over corrugations. The first trip I did with mine I smashed the fibreglass whip off the spring base. When I had a look I could see that the antenna had been hitting the top of the bull bar just above where the whip screws onto the base. I'm actually surprised it lasted as long as it did (about 200km of the Murgenella Rd in Arnhem Land). I'm now using one of those brackets which clamp onto the bar with U-bolts which works much better. If you are planning on hitting any corrugated roads you may want to do the same.
Cheers
