Collection: Video Distribution Accessories — RF Coax, Rack Mount & Headend Hardware

Pro Video Instruments accessories complete your professional video distribution installation — whether you are building an HDMI-over-coax RF headend, scaling a VeCASTER IP streaming rack, or turning compact modulators into a clean 19-inch rack system. Every accessory is designed and made in the USA, pairs with the VeCOAX and VeCASTER families, and ships with free unlimited lifetime tech support.

The Coax Combiner / Splitter is the essential RF accessory when you run more than one VeCOAX modulator. Its 12+1 bidirectional ports merge every modulator output onto a single coax cable — or split one combined feed to many TV drops — with ultra-low insertion loss for HD and 4K digital TV.

The 1RU Rack Panel mounts up to four VeCOAX MINIMOD HD modulators in one rack unit with full front-panel access to every color LCD and control port. For IP streaming, the VeCASTER RACK-PLATE-KIT mounts one or two VeCASTER encoders in a single 1RU space, and the RACK-BARS-KIT scales up to fifteen encoders (thirty channels) in 5RU with secure, airflow-friendly hardware.

These are the same accessories referenced across our modulator, streaming, and INFINIUM product pages — the proven hardware integrators use to finish a broadcast-grade coax or IP installation.

Which accessory does your headend need?

When do I need a coax combiner?

Every VeCOAX modulator outputs one RF channel on its own coax port. When you run two or more modulators, a Coax Combiner / Splitter merges those channels onto the single coax cable already running through your building. Every TV then scans the full custom channel lineup. The same device works in reverse as a low-loss splitter to fan one combined feed out to multiple coax drops.

When do I need the 1RU rack panel?

If you are mounting several VeCOAX MINIMOD units in an equipment rack, the 1RU Rack Panel holds up to four modulators in a single 19-inch rack space with front access to every color LCD — the clean, professional way to build a compact multi-channel coax headend.

VeCASTER rack plate or rack bars?

For one or two VeCASTER encoders, the RACK-PLATE-KIT is the simplest 1RU install. When you need a high-density streaming headend, step up to the RACK-BARS-KIT and mount up to fifteen VeCASTER units (thirty channels) in 5RU.

Do these work with other PVI products?

Yes. The coax combiner pairs with every VeCOAX modulator and INFINIUM coax output. The rack panel fits MINIMOD HD units. The VeCASTER rack plate and rack bars fit the full VeCASTER encoder family. All ship same-day, carry a 5-year warranty, and include free unlimited tech support from our Florida engineering team.
