LMR400 PL-259 vs RG142 Mini UHF-to-SMA: Which Ham Radio Cable Fits?

Compare the $56.98 50-foot LMR-400 cable with PL-259 ends against the $89.17 RG142 cable with Mini UHF and SMA male ends, then choose by connector match, cable format, and the $32.19 price spread.

Last updated Aug 25, 2026

For shoppers comparing coax, connectors & portable cases for a ham-radio setup, the first decision is not the cable label or price. It is whether the two ends match the radio, antenna, tuner, or other RF hardware. A lower price cannot fix a connector mismatch, and a different pairing may not suit a two-ended run. Start with the equipment-side connections, then weigh the cable format and construction details.

Quick verdict

Choose the 50Ft LMR400 PL259 UHF Male-to-Male Cable for a 50-foot run ending in PL-259/UHF male connections. Choose the RG142 Mini UHF Male-to-SMA Male Cable when those two different interfaces are required. The listed price spread is $32.19, so the connector decision comes first and the price comparison comes second.

Where each wins

LMR400 PL-259 cable: This is the clearer fit for the antenna, tuner, analyzer, or coax-switch uses named for it when the layout calls for a 50-foot feed line and matching UHF male PL-259 ends. The title's ham radio antenna wording also keeps its use case concrete. Its lower listed price is a secondary reason, not a substitute for matching the connectors.

RG142 Mini UHF-to-SMA cable: This wins the interface decision when the equipment-side connection specifically calls for Mini UHF male at one end and SMA male at the other. The silver-plated connectors and double shield are concrete construction attributes to weigh alongside the connector match. The connection requirement is different from a two-PL-259 path, so choose it for the named transition rather than for the RG142 designation alone.

Product notes

50Ft LMR400 PL259 UHF Male-to-Male Cable

50Ft LMR400 PL259 UHF Male to Male RF Coaxial Jumper Cable For Ham Radio Antenna

Choose the 50Ft LMR400 PL259 UHF Male-to-Male Cable when an antenna, tuner, analyzer, or coax switch needs a 50-foot lead for a ham-radio setup. The title's Ham Radio Antenna wording and the stated LMR-400, 50-ohm format give it a clear place in a feed-line decision. Its concrete limitation is the 50-foot format: a shorter layout may not need that much cable. It also uses PL-259 UHF male connectors at both ends, so it is not the direct Mini UHF-to-SMA male transition. That makes the cable easy to choose for a matched UHF connection, but less suitable when the equipment-side interfaces differ.

RG142 Mini UHF Male-to-SMA Male Cable

RG142 Silver Mini UHF Male to SMA MALE Coax RF Cable USA Lot

Pick the RG142 Mini UHF Male-to-SMA Male Cable when a radio or RF setup calls for those two different connector ends. The cable's silver-plated connectors, double shield, and solid silver-plated center conductor offer specific construction details to consider, while the RG142 designation keeps the choice distinct from the LMR-400 lead. Its limitation is that it does not provide two PL-259 UHF male ends, so it cannot serve as a direct substitute for a matched PL-259 run. The listed price is USD 89.17, placing it $32.19 above the other cable. Choose it for the Mini UHF-to-SMA interface itself, not merely because its cable designation is different.

Final choice by use case

  • Choose the 50Ft LMR400 PL259 UHF Male-to-Male Cable for a ham-radio antenna or related run that calls for matching PL-259/UHF male ends and fits its 50-foot format.
  • Choose the RG142 Mini UHF Male-to-SMA Male Cable when the required path is specifically Mini UHF male to SMA male, and its silver-plated, double-shielded construction is relevant to your selection.
  • Choose by interface before price: the first cable carries the lower listed price, while the second is the higher-priced choice; neither price changes the connector pairing.
