Using KVHUs patented low-profile antenna technology, the new DIRECTV-compatible TracVision A7 is the perfect in-motion solution for motorcoaches with low-clearance requirements. At 5''high, the TracVision A7 blends into the roofline of high-end coaches and RVs. For added convenience, the TracVision A7 also includes KVHUs deluxe 12V mobile receiver for DIRECTV and reception of your local programming. Note P low profile (flat) domes are ideally suited to in-motion operation and may experience rain fade from pooling water in some stationary applications.
