2 of them. Also got a little package from a fellow ham on the island of Malta

Completely different frequencies and propagation effects, but GMRSers might be suprised to learn on HF (short wave) some hams get lucky and bounce signals all the way around the world with 10 to 20 watts. Back to relevant bands and frequecies, you can communicate with the ISS with a regular 50 watt VHF or UHF transceiver. Using a Baofeng HT I have listened in on hams using the ISS repeater to make contacts with other hams. Knowing the antenna polarization and sweeping thru the frequencies made it better as did waiting for a high overhead pass.
It is about the antenna and knowing what to do with it

I have confirmed that it does give a minimal amount of help at the fringes. I also confirm that it does matter which way it faces. Apparently adds a little bit of antenna polarization.
A location where I routinely activated a repeater from 18 or 20 miles away from the top of a 14 story building I could also work the repeater from ground level with the tiger tail oriented toward or away from the repeater but not perpendicular to the repeater. It did not make my signal understandable. From the roof with the tiger tail my signal report was no detectible difference hanging down but the same + at 0° and 180° and some decrease at 90° and 270°. Without the tiger tail I could make a difference by moving to different spots on the roof. I knew exactly where to stand to get the best propagation.
If you are using a rubber duck, factory original garbage or counterfeit Nagoya a tiger tail isn't going to help as much as a buying genuine Nagoya.

Yes, the permit would actually be for breaking the ground and installing a permanent structure. The antenna nor tower is actually the permanent structure that a dugout and poured base would be.

102 works for me too, but I try to tune them ahead of time with a NVA

Only 100% symetrical ground planes don't cause propagation distortion. Don't worry that much about it. In my experience using field strength meters, mounting an antenna on a corner of a vehicle does cause the signal to be stronger across the vehicle to the opposite corner and 180° diagonally behind the vehicle. Dead center front or back sends the strongest signal in those directions, but it's only a few db. Any advantage or disadvantage would only come while the vehicle was stopped and you are making fringe contacts.
Ability to mount the antenna higher will be more helpful than where on the vehicle.

1.4 SWR means all the incorrectly tuned antenna comments are waste of inconvenienced electrons. Not to be rude, but did you guys not read that in the original comment or do you not know what it means?

There is probably a Notarubicon Youtube video on it

Write it on a piece of tape on the radio or mic until you have it memorized.

Someone once tried and it was denied, so it is proven.

No problems whatsoever, but knowing the TYT 9800's reputation, I waited until they were on sale and bought an extended warranty.
If you noticed the mic has more buttons than the normal TYT DTMF mic you are correct. I did a lot of research before I bought the 9800 and the mic upgrade was one of the things I read about multiple places, so I went ahead and did it. The mic was very inexpensive and required a minor rewire, I think it was around $20. In freezing weather the chip in the mic won't engage the transmitter until it has warmed up. If I am anxious to talk right away I have to hold it on the heat outlet for a couple of minutes the first time I transmit. After that it stays warmed up.

Antenna mount type and position

A bit louder and clearer, but you probably won't get a lot more distance. Height is might. Obstructions can't be overcome with power (unless you are lucky with refraction).
