This connector is sometimes referred to as a “UHF connector,” even though its performance at UHF frequencies is not that stellar. PL259 / SO239 – The PL259 is the male connector while the SO239 is the female counterpart. Consider the coaxial cable routing for your potential antenna locations and identify the best combination of cable type for location, routing, and loss. ![]() Still, for most VHF/UHF FM operations this capacity is much more than adequate. It combines very admirable loss figures with high flexibility for ease of routing, but it is limited in its power handling capacity to about 300 watts. Additionally, some of these larger diameter cables are produced in flexible varieties, such as Belden 9913F7. However, the larger gauge cables tend to offer the lowest loss figures. Larger gauge coax, such as RG-8, 9913, or LMR 400 is much more noticeable and is usually stiffer and somewhat more difficult to work with. However, as noted in the table above, narrow gauge cables tend to impose higher signal losses. It requires smaller holes and it fits around corners well. Narrow gauge coax such as RG-58 or RG-174 is low profile and quite flexible. Consider the local radio resources available to you and how you wish to use them, and then decide what band capability your station and antenna require for those operations.Ĭoaxial Cable Gauge: How and where you need to route your antenna coaxial cable and the length of run necessary may impact your selection of a coaxial cable gauge, or diameter. (Ditto for only 1.25-m, 70-cm, or 6-m band ops). However, if the only repeater you intend to use from your home is a 2m machine, and you have no interest in other VHF/UHF band operations, then a single band VHF antenna may be your choice. I highly recommend a dual band radio and antenna for the new Technician Class ham as a starter radio, most typically the 2-m/70-cm combo with an antenna to match. ![]() Probably the most popular combination is the 2-m/70-cm dual band scenario mentioned above, but tri-banders that include the 1.25-meter (220 MHz) band or the 6m (50 MHz) band are very popular, as well as combinations of 2-m/1.25-m, and other combinations. Single band or multi-band antenna? With multi-band radios now so readily available to hams, the majority of folks are likely to desire a multi-band antenna with which a single feed line can be used.
