Applies to: VQ4500/VQ4510 under 21955 Rev A. Keep this Tailgater generation separate from VQ4900/VQ4950 Pro, DT4400/DT4450 and KING One Pro. Historical receiver menus and satellite lists require current DISH confirmation.

Work through these checks
Separate search from usable television
Record the search result, acquisition screen and guide-loading stage separately, with the time at each transition. The manual describes these as successive stages, not one instant result. A scan completing while the guide is still loading should not be reported as an antenna that never found anything.
What the result means: Keep checks at ground level with the dome closed. Record the exact message before changing anything. Roof installation, electrical changes and internal repairs need qualified service. Confirm the current receiver procedure; do not copy historical button sequences into a different receiver.
Compare reception and authorization
If reception reaches programming but an authorization message remains, record that wording separately from a no-satellite error. Rev A identifies error 013 after inactivity as an authorization issue. Ask DISH to confirm service for the actual receiver; do not replace the antenna to resolve an account state.
What the result means: Keep checks at ground level with the dome closed. Record the exact message before changing anything. Roof installation, electrical changes and internal repairs need qualified service. Confirm the current receiver procedure; do not copy historical button sequences into a different receiver.
Test the pattern of missing channels
Keep a short list of working and failing channels and whether the failure followed travel, a move of the antenna or severe weather. The historical manual distinguishes local-channel footprint and blackout restrictions from general reception failure. Use those observations to ask the provider about current coverage and entitlement instead of guessing a replacement part.
What the result means: Keep checks at ground level with the dome closed. Record the exact message before changing anything. Roof installation, electrical changes and internal repairs need qualified service. Confirm the current receiver procedure; do not copy historical button sequences into a different receiver.
Use the primary receiver as a baseline
When only the AUX-connected receiver fails, preserve the main receiver’s channel and time of its last change. Both outputs share the main receiver’s selected satellite; the second receiver is not an independent antenna. Give support both receiver models, messages and this timeline so the shared selection can be checked before treating AUX as defective.
What the result means: Keep checks at ground level with the dome closed. Record the exact message before changing anything. Roof installation, electrical changes and internal repairs need qualified service. Confirm the current receiver procedure; do not copy historical button sequences into a different receiver.
When to stop and get help
Keep checks at ground level with the dome closed. Record the exact message before changing anything. Roof installation, electrical changes and internal repairs need qualified service. Confirm the current receiver procedure; do not copy historical button sequences into a different receiver.
What to tell support
