Q: 1. I need to replace my antennas, where can I find just those two parts?

A: You can use the Lectrosonics AMJKIT Whip Antenna for UM and SM Beltpacks, SR Receivers (B&H # LEAMJKIT) to replace the antennas for the Lectrosonics SRc Dual-Channel Slot-Mount ENG Receiver. The kit includes cutting template and color caps. You will need two of the antennas.

Q: 2. Many thanks to all. I have the Phottix Indy 500 and the Canon Odin trigger, but I also have a Pentax 645Z that I like using in the Studio environment. Question is: Will the Trigger portion of the Vello work with the Indy500, I know that if it does it will only be in manual mode, but its better using a long cable. At least the Profotos have a separate trigger for Non Canon/Nikon/Sony cameras...? Thank you .

A: If you plan to use the Vello remotes, you would need the FreeWave LR Wireless Flash Trigger connected to your camera's hot shoe or PC sync terminal and the FreeWave LR Receiver connected to the monolight's 3.5mm miniphone sync terminal. The Vello trigger may only be used with the Vello receiver. The remote built into the Phottix Indra500 is a Phottix Odin receiver, and is only compatible with Phottix's Odin transmitter for Nikon or Canon, or the Phottix Strato II for manual usage (Phottix Strato II is not currently carried at B&H).

Q: 5. Will this set of 3 components work in high speed sync with a Nikon D500( up to 1/8000 second)?

A: All these triggers do are trip the strobes.. the rest is up to the camera and strobes. TTL does not work with my Nikon D750. The strobe has to be on Manual for it to trigger it.

Q: 6. Is this compatible with older Lectro transmitters (e.g. UM400a)?

A: Yes, the Lectrosonics SRc Dual-Channel Slot-Mount ENG Receiver can be used with older Lectrosonics transmitters that operate on the same frequency band. The receiver has different compatibility mode settings for use with transmitters other than those from the Lectrosonics Digital Hybrid Wireless series.

Q: 7. I have a Nikon D7100 and a Neweer Speedlite 750ii Flash and can't get it to work. Any suggestions?

Q: 9. Will this work for Canon 470ex-ai speedlite?

A: Yes, the Vello FreeWave LR Wireless Flash Trigger and Receiver Kit may be used with the Canon Speedlite 470EX-AI. However, as the Vello FreeWave LR Wireless Flash Trigger and Receiver Kit is a manual radio remote kit, you would have to set the flash output on the Canon Speedlite 470EX-AI manually.

Q: 10. Wanting to use on my OM-D E-M5 II, but to trigger my Canon speed lights. I have 2 600EX-RT's. As long as the speed lights are manual mode, will it trigger them? and would the speed lights need to be set to any sort of slave mode?

A: Use the speed lights in manual, connect each speed light to the Vello receiver, put the trigger on your camera's hotshe make sure the trigger and receiver are on the same channel and shoot away. there is no TTL and the speed lights need not be in any slave mode. This is manual setting only. Use a light meter if need be to determine exposure and you should be fine.
