GRA-7350TC 3/8" x24 CB HF 3.5MHz 7-30MHz/50MHz Broadband Telescopic Portable Antenna
- The antenna is divided into three sections. Includes extended 3.5MHz coil parts. The top retractable part is made of high-quality stainless steel. Made of FRP at the bottom.
- This ham radio antenna is light and portable. At the same time, it is strong and durable. Suitable for all kinds of outdoor occasions.
- Compact and lightweight portable antenna for 3.5 to 54 MHz. The antenna is tuned by moving a solid tap on the inner coil. Because the antenna has reasonabley low SWR an ATU is not necessary in most cases.
- This is very convenient and practical when this antenna is set up in GRA-ULT01 MK2.
Compact and lightweight portable antenna for 7 to 54 MHz. The mounting coil parts can be extended to use 3.5MHz. The antenna is tuned by moving a solid tap on the inner coil. Because the antenna has reasonabley low SWR an ATU is not necessary in most cases.
Ieal for holidays or hiking just use an additional short thin wire of only a few meters length as a counterpoise.
． It is easy to adjust frequency by up-down of the coil part and on antenna tuner.
． When operation on 50MHz please use lower telescopic length into 1090mm.
． Light and flexible FRP is used.It is easy to carry.
．3.5MHz can be expanded by adding one more part.
．Install the bracket where the grounding earth can be taken.( gutter mount,trunk lid etc)
Intall the antenna at the car roof by the magnet base and GRA-MAT50 (Magnet Antenna Grounding Sheet).
Set the magnet base on the wood table and install the antenna with some approx. 10m ground wires. Intall the antenna at the metal handrail where the grounding earth can be taken.
．The SWR is not lower than 1.5 depending on the conditions. In that case, please improve the earth conditions or change the installation plaase use an antenna tuner together with the GRA-7350TC.
．het transmission for the adjustment has to be performed with as low RF power as possable with the antenna tuner.If the adjustment is not completed, move the coil up or down and adjust the frequency again.
．If tuning is OK,increase the power until operating power. (Max Power rating: 130W SSB)
．When adjusting 50MHz band, put the coil part down and remove the upper element. Use the lower element only.
