The Lectrosonics UHF Filter Amplifier Module Block 22-23provides a unique, high performance solution for antenna systems requiring long cable runs or distribution to multiple receivers or locations. The unit can be used to apply RF gain at the antenna ahead of a long run of coaxial cable to compensate for signal loss through the cable. A compact, high performance multicoupler can also be configured using the UFM50 ahead of an RF splitter to offset the loss through the splitter.

The UFM50 design places RF filtering before gain to minimize intermodulation (IM) products and prevent overload. Two transmission line ceramic resonators at the input provide filtering with a 50 MHz bandwidth. Following the filters, 12dB of gain is applied with a high quality GasFET RF amplifier with an excellent +41dBm IP3. The result is outstanding RF performance without IM or overload problems.

A switching regulator is used in the power supply to control current consumption over an input voltage range of 8-16 volts. The regulator maintains low current consumption and low heat dissipation which is especially useful in portable audio mixing common in field production and ENG.

The UFM50 can be powered from external DC or via phantom power through a coaxial cable connected to a multicoupler. The housing is constructed of cast aluminum with a brushed aluminum cover plate. Two rugged BNC connectors and a threaded, locking power jack provide secure connections for rugged field conditions and for long-term installations.

Q: 1. Will I be able to fit two Nikon D810 with battery grips along with 80-400mm, 28-70mm, 18-35mm, 300mm, 60mm lens?

A: I would move up to the Anvil 27.

Q: 2. Will this work with the Nikon 950 as a dust cover? I live in an area that is quite windy.

A: The Ruggard Fabric Rain Shield Large (23") will help protect your gear from dust, but this is much too large for the P950; the Small Rain Shield would be the right size for the P950.

Q: 3. Are these radios good for indoor as well as outdoor use?

A: Yes. You are able to use these both outdoor and indoor. Operating conditions:Open areas without obstructions is up to 5 miles (8 km)Residential areas near buildings is up to 1.5 miles (2.4 km)In steel and/or concrete reinforced buildings the range is up to 225,000 sq.ft (20,900 sq.m)The range in high-rise buildings is up to 17 floors

Q: 4. what is the difference between the Tamarac anvil 23 and 27?

A: The Tamrac Anvil 23 is 17.3 inches tall and the Anvil 27 is 19.7 inches tall for the interior. All other interior dimensions are the same but because of the added height, the Anvil 27 would be able to hold a longer lens and/or more equipment.

Q: 5. How does this Ruggard Rain shield large, compare with the Think Tank Emergency Rain cover large?

A: In comparing the large sizes in each model, the Think Tank Emergency Rain Cover is longer at 27.5" but only has a diameter of 7.8". The Ruggard Fabric Rain Shield Large is only 23" long but accepts a slightly wider diameter of 8".

Q: 6. Im interested in a purchase of a steadicam vest and I would like to know, whats the difference between EXOVEST and GOOFY EXOVEST?

A: Whether you are RIGHT HANDED or LEFT HANDED all you need to do is flip the BLOCK. This apply's to the either BLOCK; large of small block.

Q: 7. will this fit a Nikon d810 with a 70-200mm f/2.8 VR 11 lens ?

A: The small Ruggard fits my Nikon d5500 with a Nikon AF-S DX NIKKOR 18-300mm f/3.5-6.3G lens with room to spare. The Ruggard kept my equipment dry in windy and waterfall mist conditions. Very pleased with it.

Q: 8. Are you able to hear incoming calls while around heavy equipment?

A: Yes, you will not have any connection issues when receiving calls around heavy machinery. If you are asking about if the ringer is loud enough for heavy industrial environments, that depends on the ambient noise level of the area.

Q: 9. Is there a vibrate feature?

A: No, you are alerted to an incoming call by a bell tone and flashing light.

Q: 10. Would any of these Ruggard Rain Shields work with a Sony PXW-X70 camcorder? I've looked at the listed accessories on the X70 page but aren't crazy about any of them (too expensive). Thanks.

A: Though it isn't necessarily made for the Sony PXW-X70, it will cover it and it will work to protect it when shooting in the rain.
