Cheap UHF Directors Monitor


Recommended Posts

  • Premium Members

Jess,

 

I have that monitor and I love it!! I will get an IDX plate from batteriesforbroadcast.com and will make handles for them and put a baby pin on the bottom. They have a kick stand and screw in base very good for the price!! I actually bought 2 of them, one of the director and one for an AC or a dolly grip for when I'm on the rickshaw or doing driving shots...

I have been using the Axion for a little while now and I would say I have more of a love hate relationship with it. Sometimes the signal will cut out, I think mainly due to interference or something and the monitor will go into a power save mode and stop looking for it. Changing channels then changing back usually causes it to get it again but it can be annoying. In some locations I have not had it do this a single time, while in others it caused more serious problems. Otherwise it is great and if the director can remember to turn it off while not using it the built in battery actually lasts a good while.

 

Be careful with that IDX plate. You most likely will need a voltage regulator in order to not fry it. I have been going back and forth between adding an anton bauer plate or using smaller batteries of some sort velcroed to the back

I had the same problem on Friday with mine. The signal would cut out at about 100 feet. Not good at all. Any recommendations on antennas I should use. Maybe a better one on the transmitter? I'm using the RF links transmitter. Thoughts? Ideas?

 

thanks,

Kat

So I finally wired my monitors and made some handles for them check it out...

 

With the IDX battery on there the monitor will last about 5 hours then the internal battery will last another 1.5 hours...

 

I can modify anyone's monitor or make one for anyone if they would like... let me know

On my current show two of the lovely ladies from hair and makeup are using current generation Axions and I've had a chance to sniff them out a bit. It's a nice package but I have indeed seen what others have mentioned here for drawbacks, i.e. the blue screen when signal cuts out is annoying (there used to be a menu item on similar monitors that would toggle this as an option, too bad they didn't include here). It seems to be able to resize to different formats (stretch, zoom etc) but you have to enable the desired mode in the menu.

 

Most importantly though, the reception seems quite spotty compared to other monitors we are using around the set, which is consistent with some other's findings here. That would be the major drawback to these units, I would think.

Sorry to revive such an old post but I thought you guys might like this setup for my UHF/VHF director's monitor. I used an Axion LCD and Lenmar battery pack. So far this has worked ok with my Modulus 3000. Occasionally I do get drop out leaving the monitor with a blue screen. I went to my local bicycle dealer to purchase handle bar wrap for the bracket grips.

the regulator needs to be heat sink mounted to metal and needs small tantalum capacitors at in and output so the RF the regulator generates does not get into the front-end of the receiver and degenerate sensitivity.

 

there is 30 page document on Tx-Rx on my site, write if the link does not work: A roundup of all transmitters, HD and SD, 25 pages. This private document:

As long as we are reviving the thread I would just like to say that I have been using a Camos for a while now and it is definitely worth the extra money. The receiver in it is far better than that in any of the other monitors I have tried. For some reason the reception on the Axion was getting worse and worse and I don't even bother bringing it as a backup anymore because it was more of a headache than it was worth.

UHF TV receivers:

All need our custom screen protectors. The art here is in the application not the $5 piece of low reflective plastic by Photo-don. http://www.photodon.com/c/LCD-Protective-Films.html All TV when run on external 16V Lithiums need regulators that have to be properly heat sunk and filtered for high frequency noise.

 

Sony cheap ass battery adapter, it works but it breaks easily. Its 7.2V of course. Some with 6 to 12V switching are available but still break and get hot.

http://www.bhphotovideo.com/c/product/646135-REG/Ikan_AC_107S_AC_107S_Sony_Battery_Adapter.html

Nebtec makes some too, make sure they have the external heatsink.

 

Small TV

Don’t recommend the Liliputs as they have awkward tuning. The channel no. on the screen is a consecutive no. Not a real channel. You have to rescan all to find one new ch.

The Haier was more sensitive earlier than now. It comes in 6V and 12V versions: 7” and 10”. Tuning is good. Earlier models were prone to bad controls; recent models had some bad remote controls. Internal Batt good for 2 hours or so.

. .people would not be buying these things if they didn't also perform "insanely great" say the Apple heads…. I say that is spin at its sickest. To talk like that about anything but your trained cat is just soooooooooooooooooo stuuuupid.
