Base station guides

When vehicle mobile still cannot hold the net from home, or you need regional HF contingency, a fixed shack or mast install is the next layer. These guides cover power, antennas, and emcomm role — not tower engineering.

Mobile vs base? Mobiles move with you. Base stations stay put with larger antennas and duty-cycle power. Most property owners add VHF/UHF base first; HF base follows a General-class upgrade. Compare on radio reference.

HF all-band (160m–70cm receive) Icom IC-7300 / HF base SDR General or Extra for most HF TX · Upper ($1,000–$1,200)

Most common first HF base in modern shacks — built-in tuner, spectrum scope, and clean receiver for regional NVIS nets, Winlink, and emcomm liaison work.

Open base guide → HF 160m–10m Xiegu G90 / portable HF base General or Extra for most HF TX · Mid ($500–$650)

Compact HF transceiver with internal antenna tuner — popular for field base, go-box HF, and property owners who want NVIS without a full rack shack.

Open base guide → HF + 2m + 70cm Yaesu FT-991A / HF+VHF+UHF base Technician (VHF/UHF) + General (HF) · Upper ($850–$1,100)

One-box base station covering emcomm FM nets and HF traffic — strong choice for General-class operators building a single shack that serves both local repeaters and regional HF.

Open base guide → 2m / 70cm base antenna Diamond X50A / 2m+70cm base vertical Technician or higher (antenna only — pair with radio) · Budget ($90–$120 antenna + mount)

Standard dual-band base vertical for home nets — bigger ERP than any handheld or most mobile installs when mounted high and clear.
