When you say mobile, do you mean portable given the reference to horizontal dipoles, as opposed actually mobile out of a vehicle?

I tend to use an autotune antenna in the 4x4, which with the standard whip will give me 80-10, and with a longer whip, 160m, but very poor efficiency on the lower bands obviously.

For 80m NVIS, I have a 45 degree adapter so can angle the whip over the front of the vehicle to shoot the pattern more vertically.  Same concept as the military use if you look at the way the HF antennas are bent forward.

Parked up, it's a squid/fishing/telescopic pole and then an EFHW which you can orientate to favour the band and type of propagation you want.

Interesting.  I’m running a Codan 9350 on the back of the Landrover, as an ATAS is nowhere near rugged enough for proper 4WD use in the middle of nowhere.  That’s hooked up to an IC-7000 to give me VHF and UHF as well as HF in the one radio.  If I was making proper use of our HF Landmobile (non-Amateur) networks out here, I’d swap it for the Codan so I had Selcall and ALE, as well as GPS positioning updates and could use the phone interconnect service most of the networks run.

We don’t get 60m here, so 80m is the norm for NVIS unless the MUF is high enough for 40m

That is a nice if a tad expensive antenna, particularly like the Codan NVIS Kit for 1.6MHz to 12MHz, not sure I could fit something like that to my Toyota Avensis Estate, as all the bumpers are plastic, I don't currently have a 4x4, well not a true one, I'm thinking of fitting these NVIS Dipoles to my 2000 Audi S3 Quattro using the Audi Roof Rack (Steel).  I am suspicious that the wife is starting to see through everything I buy as being 'just a couple of quid dear', she may be cottoning on.

I'm also banned from putting ANYTHING in the wife's SUV!  Very Happy

Those antennas can be had quite cheap s/h (at least here, where they're made), and the police also run them on plastic bumpered saloon and estate cars by a bracket connected to the tow hitch.

For on-road use, I'd use and ATAS as long as I didn't need 80m, or Hamsticks if I predominantly used one or two bands.  None of whcih is any use for NVIS, of course.
