The Blonder Tongue CATV Modulator SAW Filtering Channel 58from Blonder Tongue CATV Modulator SAW Filtering Channel 58is 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.

Q: 1. Does this cap fits a Canon 50mm 1.4 lens?

A: As the Canon EF 50mm f/1.4 USM lens uses 58mm filter threads, yes, the Canon E-58 II 58mm Lens Cap, B&H # CALC58, would be compatible for use with the Canon EF 50mm f/1.4 USM lens.

Q: 2. Does this cap fits a canon 50mm 1.4 lens? thank you!

A: As the Canon EF 50mm f/1.4 USM lens uses 58mm filter threads, yes, the Canon E-58 II 58mm Lens Cap, B&H # CALC58, would be compatible for use with the Canon EF 50mm f/1.4 USM lens.

Q: 3. Will this fit Canon G7x?

A: The lens retracts into the camera body, no cap is necessary.

Q: 4. 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.

Q: 5. Does this lens cap fit my sx50hs ?

A: Your Canon PowerShot SX50 HS needs the Canon Filter Adapter FA-DC67A B&H # CAFADC67A to take 67mm filters and lens caps. Here is the correct one for you. Canon E-67 II 67mm Lens Cap B&H # CALC67.

Q: 6. Is this the correct size for my Canon Vixia HFG30?

A: The Canon E-58 II Lens Cap is the correct cap for the Canon VIXIA HF G30 Full HD Camcorder.

Q: 7. Is this (the E-58 II 58mm lens cap) the correct replacement cap for the Canon XA10 cameras?

A: This lens cap should work well with the Canon XA10 camcorder as it is designed for 58mm Canon lenses.

Q: 8. will the e-58 ll 58 mm lens cap work for canon rebel t7? The lens is 18-55 mm but 58mm is shown for lens cap I guess

A: The Canon EF-S 18-55mm f/3.5-5.6 IS II Lens normally included with the Canon EOS Rebel T7 can accept this Canon E-58 II 58mm Lens Cap.

Q: 9. Will this Lens cap fit Canon Powershot SX530HS?

A: The Canon E-58 II 58mm Lens Cap will not fit the Canon PowerShot SX530 HS Digital Camera. If you need a replacement lens cap you would need to get the Canon Filter Adapter FA-DC67A and a 67mm lens cap instead.

Q: 10. Will this fit the Canon EF 28-70mm f3.5-4.5 II Lens (1988) but which takes a 52mm filter?

[CATV channel 58] Much better picture than using VCR for modulator and Radio Shack RF switcher. No lines much better picture. I only use Blonder-Tongue for modulators. 5
