The Blonder Tongue CATV Modulator SAW Filter Channel 54from Blonder Tongue CATV Modulator SAW Filter Channel 54is an all-solid-state audio/video modulator that provides a modulated visual and aural RF carrier output on one specific CATV channel. The unit modulates the audio and video inputs and provides the requested RF CATV channel output for use in a CATV, MATV or SMATV system. The modulator accepts standard (sync negative) polarity video at a 0.7-2.5V peak to peak level from sources such as a TV camera, video tape recorder, TV demodulator or satellite receiver.

The modulator features a +55dBmV RF output level, and an IF SAW filtering for adjacent channel operation. All aeronautical channels are offset positive with a tolerance of ±5kHz as required by FCC 21006. All level controls are located on the front panel. The RF level control provides up to +55dBmV output. The video modulator control sets the depth of modulation for 87.5% over an input video level range from 0.7VP/p to 2.5VP/p. An audio modulation control permits adjustment for ±25kHz peak deviation of the aural carrier.

Related Questions and Answers

Q: 1. If the max length of the pantograph is 6'6", if my ceiling is 11'6" the LOWEST I can pull the pantograph down is still 5', yes? In some cases I may want to go just a little lower...Perhaps there is a way to mount the rail system a little lower?

A: You can mount it a little lower with extension # MALSEEB

Q: 2. Can I add more pantographs to this system if I want to? Additional lights and or a mic?

A: You can add more pantographs to this system, but that will prevent full movement of the pantographs that are already installed.

Q: 3. My ceilings are 19 feet high. There are times when I need the light pretty close to the ground (babies). How can I get pantographs that extend much longer? I'm not really interested in mounting the rail system lower with extensions, I think that will look really messy.

A: Unfortunately, the kits only include the standard pantographs. However, the Manfrotto Pantograph - Extra Long, BH # MAFF3514N86 can be purchased separately as well as the other components in this kit. https://bhpho.to/3qWD71H

Q: 4. Can this fit an attached 70-200 ?

A: Yes.

Q: 5. Is this compatible with the Canon 18-55mm IS II lens?

A: The Vello EW-54 Dedicated Lens Hood is only compatible with the STM lens. It is not compatible with the 18-55mm lens that does not have the STM designation or feature.

Q: 6. Can I get an extra & longer mobile rail?

A: The rails come in three sizes. The 3 meter is FF6003B, the 4 meter is FF6004B and the 5 meter is FF6005B

Q: 7. Would an 8-foot ceiling be too low since these will hang a minimum of 1'6"?

A: Yes it would be best if the ceiling is beyond 8 feet.

Q: 8. What do you think of this bag? Sturdy? Good for a SONY A6100 with grip and a 24-105 lens attached. Pockets? Ample . Quality?

A: The Ruggard Journey 54 DSLR Shoulder Bag has a sufficient amount of space to carry the Sony a6100 Mirrorless Camera (B&H # SOA6100) with the Vello BG-S4-2 Battery Grip for Sony Alpha a6100/a6300/a6400 Series Cameras (B&H # VEBGS42). Additionally, the Sony FE 24-105mm f/4 G OSS Lens (B&H # SO241054G) and an extra lens would fit as well. The pockets are versatile for memory cards, cable, and other small miscellaneous items. The material is made of polyester, which is popular for its incredibly high strength and durability. Overall, this bag should accommodate the needs of a standard camera bag.

Q: 9. is there a mounting and installation guide I can access somewhere?

A: You may contact Manfrotto directly for assistance with proper installation of the Sky Track Top System 54. They can be reached using the following link: http://bit.ly/1KPDX9C

Q: 10. Does this device require power if used for POE cameras?

A: This will not transmit any POE. This is meant to convert a COAX signal and allow you to transmit the signal over Cat5.

[-90 dBc] Great device, bought to fix a ground loop hum between my catv coax coming into the house and my other audio-video equipment. So now no more hum and the video reception quality did not degrade. 5
