best tripod for the arrow II handheld antenna
What is best tripod for the arrow II handheld antenna ?
I find a biped to work best with an arrow antenna. Works great for aiming and polarity matching.

Mike's being funny. :)
I used to use a $10 tripod I got from the Goodwill. The main thing I appreciated about it was its ability to do axial rotation -- think: camera on its side. When the Arrow was attached, I would us that feature to rotate the Arrow along its axis.
Nowadays I do what Mike does: I hold the Arrow in my hand. It takes some time to become comfortable with holding the antenna correctly while adjusting for Doppler and pressing the mic button, but after some practice I found it to be the most efficient way. It's counterintuitive, but using your hand to orient the antenna is very fast and flexible.

On a more serious note there are advantages to hand holding the Arrow even if it feels like you need to be an octopus to pull it off. There's a certain hand ear coordination that seems to come naturally when matching polarity by simply twisting your wrist. This advantage alone can be significant over fixed polarity or polarity matching by some mechanical means. The only time I would recommend a tripod is if there is some physical reason for not being able to hold it.
Often times people go the tripod route because it seems like too many things are going on at once. One common pitfall is trying to log while a pass is in progress, usually on paper. A better solution is to record the audio for playback later. A simple voice recorder or even a smartphone works great. If using a voice recorder be sure to set the clock to UTC, timestamps will make logging a lot easier.
Another way to free up a hand is to use a boom mic headset with a foot switch for PTT. By doing this you free up your hand to operate the VFO(s).
Like Bryan pointed out, it can seem counterintuitive that holding the antenna can make things easier but when you evaluate the rest of your station you may find other ways to free yourself to aim.
If you find that there's just simply no way to operate without a tripod then maybe you can describe the difficulties you face. I've seen many clever designs, each with their own advantages and disadvantages making them each suitable to a different crowd. Let us know what you're looking to get out of a tripod setup, I'm sure there are plenty of people willing to share their solutions.

Apologies if this is a dumb question, but it is from a relative newcomer to this field . . . :) Has any research been carried out on the (medical) safety of hand-held antennas such as the Arrow whilst transmitting? I understand the power is relatively low, but unlike say a mobile (cell) phone, average power I imagine will be much higher? Are there any measurements of field strength this close to the driven element and any assessments of the risks?

Julian,
No apologies necessary, there's absolutely nothing wrong with asking questions.
As far as research goes, I'm not aware of what studies have been done. This is probably because it has been of little concern to me based on what I know about RF and the design of Yagi-Uda antennas.
RF is non-ionizing meaning it is incapable of causing any changes at a molecular level. RF only has the ability to cause heating of objects in its vicinity. That said, I'm not sure it's even possible to feed an arrow with enough power to cause any real heating without damaging the antenna first.
We can look at why antennas like this are used in the first place. These antennas have a good front to back ratio that directs the RF away from the handle. If we compare the radiation pattern of an arrow to that of a standard rubber duck antenna you'll see that much less energy is directed at the user. Personally, if I was concerned with exposure I would worry more about a 1/4 wave whip than a Yagi. Of course that assumes I don't have the Yagi pointed at myself. :)
If you would like more on the topic this page may be a good starting point https://www.fcc.gov/engineering-technology/electromagnetic-compatibility-div...
Others in the group may know of studies done on the subject, I'm sure they'll share if they do.

One way to quantify RF exposure is with a tool published by VK3UM mostly for the EME community where radio power levels are higher than what is used for low earth orbit satellites:

Zach,
Interesting that you mention high power RF safety. The FCC will require all hams to submit an RF safety certification with license renewals. Hams will need to submit documentation supporting the safety of their stations and possibly keep field strength monitoring equipment at the QTH.
The strictest limits will be placed in 50 MHz to 500 MHz range since the human body absorbs RFI energy efficiently in this frequency range.
This should affect small satellite stations but will affect EME class station nestled in neighborhoods.

Paul,
I suspect you meant "should not" in that last sentence.
For those of you not familiar with these regulations:
http://www.arrl.org/fcc-rf-exposure-regulations-the-station-evaluation
At 70cm, stations are assumed, by the FCC, to be meeting the exposure guidelines with up to 70 watts of power input to the antenna. There is no language about EIRP, which, strangely, is what really matters.
I'd much rather stand next to a horizontal dipole radiating 1.5kW than be in the boresight of an EME array at 70W.
An interesting NIH paper which summarizes the effects of RF exposure:
https://www.ncbi.nlm.nih.gov/books/NBK208983/
I think I'll stick to limiting my extra-crispy bacon intake to the weekends. ;-)

I prefer holding the antenna myself but whatever you get make sure it's heavy enough to not fall over from the weight of the antenna. You may need a counterweight on the end of the antenna and/or something hung off the inside center of the tripod if it has a hook to do that like some do.
You should know the back of the antenna boom has been tapped for the standard tripod mount screw, however the boom doesnt provide a lot of "depth" or threads to really hold it well. Some people clamp the boom to their tripod for extra security.
The best tripod setup I've seen is the one John, K8YSE has.
I believe he had a DJ speaker stand (speaker tripod) and an extra half arrow boom section from a backpacker Arrow stuck in his main arrow, with the extra section stuck in a tube which was fixed to the tripod. The extra section rotated inside the tube allowing for easy polarity switching. With the antenna sticking out farther away from the tripod than it otherwise would without the extra section, its elements didn't hit the tripod.
It was big though, so maybe not the best depending on your use case.
How do you plan to use it? On the back of your porch/in yard, roving, etc. etc?
