Updated Nov 2026Comet CA-2X4SRNMO Dual-Band Mobile vs Comet SS-460SBNMO Dual-Band Mobile
Our pick
Comet SS-460SBNMO Dual-Band Mobile$59.99
The CA-2X4SR is the clear winner for dual-band mobile work, despite costing $35 more.
The decisive factor is VHF performance. The CA-2X4SR's half-wave design at 146 MHz delivers 3.5 dBi, a genuine advantage for 2-meter operations. The SS-460SB's quarter-wave VHF element produces only 1.6 dBi, which is noticeably compromised. On UHF, both antennas perform similarly with the CA-2X4SR at 5.4 dBi versus the SS-460SB at 4.9 dBi, but the VHF gap is the larger practical difference for most operators.
The SS-460SB's main appeal is its compact 470mm length and lower price point. Its shorter footprint suits space-constrained installations like small vehicles or boats. However, the 0.23 wavelength VHF element is electrically short and will underperform without exceptionally good ground plane conditions.
Buy the CA-2X4SR if you regularly work 2-meter repeaters or nets; the superior VHF gain justifies the investment. Buy the SS-460SB only if mounting space is critical and you can accept compromised 2-meter performance.
For most mobile operators balancing performance and cost, the CA-2X4SR remains the better choice.
By use case
Which should you buy?
Fixed mobile install where 2m reach matters most
Its longer VHF element gives it the stronger realistic 2m gain of the pair, which suits fixed mounts where reach comes first.
CA-2X4SRNMO70cm-first operator working repeaters at range
Its longer multi-wavelength UHF element delivers the higher realistic 70cm gain, helping with distant repeater access.
CA-2X4SRNMODaily commuter who values a compact whip
At 470mm it is far easier to live with on everyday trips and keeps the antenna out of the way.
SS-460SBNMOOwner with garage or drive-through clearance limits
Its shorter length clears low parking structures where the longer 1016mm whip cannot go.
SS-460SBNMOBudget-conscious first upgrade from a stock whip
It costs less than the longer Comet while still providing a reasonable dual-band gain step over a rubber duck.
