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

🎯 Smart POTA Coax Recommendation

For most activators:

25 ft RG-8X
Flexible
Known-good connectors

Easy to pack

🛠️ Field Tips That Matter More Than Coax Brand

Keep connectors off wet ground
Don’t coil tight loops
Strain-relieve at the radio
Pack one known-good spare

🧠 Final Brew & Activate Wisdom

A great antenna with average coax beats
average antenna with fancy coax — every time.
