Greetings From High Mountain Radio !
This is another of my quality FM broadcast accessory offerings !
This is a 'Ferrite Type' of RF Choke, which when inserted into your 50 Ohm coaxial cable transmission line prevents your coaxial cable from radiating RF along the outer braided conductor of the cable, thus preventing dangerous high VSWR (Reflected RF Power) back to the output of your transmitter. If this reflected RF energy is high enough, it may prevent your transmitter from coming online at all and can easily destroy your transmitter's final output transistor !
These RF Chokes are 100% effective in preventing this from occurring and is especially necessary when feeding a 'Ground Plane' type of antenna with 50 ohm coaxial cable !
This unwanted, radiated RF energy along the braided conductor of your coaxial cable will cause high VSWR (SWR) readings and when attempting to tune your antenna for a proper match, will surely drive you crazy ! I have seen, time and again, folks blame their antennas due to their inability to obtain a proper match to their antenna, when in fact, the root cause is most often attributed to this spurious RF energy escaping along the braided conductor !
This RF Choke / Filter is constructed from Belden RG-9913 50 Ohm Coaxial Cable. The pictured choke utilizes Type 'PL-259' Silver Plated, Teflon Insulated Male connectors at opposing ends for easy insertion into your coaxial cable transmission line AT THE ANTENNA FEEDPOINT !
Since each RF choke is custom made, feel free to message me with your particular connector requirements, I can fabricate any type of RF choke to fit your requirements !
ALL of the connectors utilized in the fabrication of these RF chokes are manufactured by Amphenol Corp., only of the highest quality silver-plated - teflon insulated manufacture which meet and exceed military (MIL) standard specifications !
$39.00 + $5.00 USPS Priority Shipping to Continental USA only. For other destinations please contact me first for a price quote to your location.
I have included a representative image of this accessory RF choke for your perusal. Feel free to message me here on this forum with any and all questions, I would be most happy to assist you with any issues !
73... Spooky...
