POTA COAX CHEAT SHEET
“The Hose Between Your Radio and the Antenna”

  * What Is Coax? (Super Simple)
  * Radio makes the signal
  * Antenna sends it into the air
  * Coax connects the two

👉 Coax doesn’t create a signal — it just tries not to lose it

The Coax = Hose Rule

  * Shorter hose = less leak
  * Thicker hose = less leak
  * Any hose still works

The 3 Rules of POTA Coax
Rule #1: Shorter Is Better

  * 10 ft > 25 ft > 50 ft
  * Don’t carry extra length “just in case”

Rule #2: Condition Beats Brand

  * Dry inside
  * No cracks
  * Good connectors
  * No mystery eBay specials

Rule #3: Reliability > Perfection

  * A working cable beats “the best cable” left at home

====== 🧵 Common Coax Types (Plain English) ======

Coax Type: What It Means for POTA
  * RG-58	Skinny, light, works fine for short runs
  * RG-8X	POTA sweet spot — flexible & low loss
  * LMR-240	Nice upgrade, still portable
  * LMR-400	Heavy, stiff, usually overkill for HF POTA

Rule of thumb:

  * If your coax weighs more than your radio… rethink it.

Does Better Coax Make You Louder?

  * HF + short runs (most POTA):
  * Difference is usually small
  * VHF/UHF or long runs:
  * Better coax helps more

Coax preserves signal — it does NOT magically boost it

  * ❌ POTA Coax Myths (Busted)
  * ❌ “You need premium coax to activate”
  * ➡️ False — people activate with wire antennas and QRP daily
  * ❌ “LMR-400 will fix my signal”
  * ➡️ False — antenna problems stay antenna problems
  * ❌ “Cheap coax is useless”
  * ➡️ False — damaged coax is useless
