Frequency Selection

Step 1 · Frequency selection & inventory

ZIP code US 5-digit

This version uses a tiny baked-in DTV dataset for illustration. Replace getDtvChannelsForZip() with your FCC / RabbitEars / internal tool for real use.

Intermod safety profile Wider = less stupid, fewer freqs

3rd-order (2f₁−f₂, etc.) 5th-order Triple-beat (2f₁±f₂±f₃)

These toggles widen the “no-fly zone” around each TV carrier to approximate how conservative you want to be. This is not a full intermod calculator (yet).

Add inventory blocks

Quantity in this block e.g. 8 x Axient G57, 16 x ULX-D G50, etc.

Brand

System / Line

Band split Hardware tuning range (MHz)

Build up the full “wish list” here (e.g. 8 AD G57, 16 ULX-D G50, 8 EW-D R1, 8 PSM G10, 4 MTK982). Then run the stupid check on the whole plan.

Requested inventory Grouped by band split

No blocks added yet. Use Add to plan above.

Rule of thumb used here: assumes an equidistant grid at ~600 kHz spacing for digital systems. Real-world channel counts will depend on your actual coordination, antenna system, and headroom.

The planner here is meant as a quick-and-dirty PM tool. Final coordination still belongs in Wireless Workbench, WSM, etc.
