#HamRadio question: What types of #RF cable to buy and from where.

Low power < 1 watt
700 M to 5Ghz typical
DC to 6G sometimes.
Low loss is nice
50 Ω

Specific uses
1) making #antennas with matching or stubs.
Indoor and outdoor.
900 mhz #yagi
900 mhz folded #dipole

2) connecting antennas on patio to indoor radio.

( 900 mhz, UV / weather resistant outdoor, fire resistant indoor. Possibly flat cable at door. Lightning arr.)

3) connecting boards together indoors (filters, amps, SDR, etc)

What I think that requires:

5 feet of moderately stiff cable for making antennas, #LMR 240/400 or equiv?

10-20 feet of low-loss outdoor cable (not buried)

1-2 feet of thin / flat cable to pass around door.

10-20 feet low-loss indoor cable. Fire resistant?

10 feet thinner flexible indoor cable to interconnect boards.

Tools for cutting & crimping. SMA, RPSma, but ideally also other types (TNC, N, maybe BNC, maybe ufl)

📡 Ah, yes, the granddaddy of all #antennas that no one asked for! Finn spent a decade constructing this colossal contraption in his backyard—because nothing screams midlife crisis like a 32x17 #Yagi monstrosity. 🤦‍♂️ Now he can talk to the moon while the rest of us are stuck debating if we should upgrade our Wi-Fi routers. 🌙📶

I’ll be camping in West Virginia in EM97 this week. Going to try to work the #MagicBand with this “thrift store” ham stick dipole and a QMX+.

Is #WestVirginia rare in others’ logs? I hadn’t been able to get it in my last 1.5 years as a Technician.
