Playing with a radio intercom, many people buy an antenna in order to have better reception.
Many people mention the Diamond Antenna the most, which is said to be effective but expensive.Better choose is Harvest antenna, which has a high cost-effectiveness. The well-known Harvest SRH775 and 771 antennas are said to have better performance, longer and softer, but due to its non retractable nature, it is slightly inconvenient to carry. 775 is retractable and more expensive than 771, some say it is easy to break.
Finally, for portability, we chose the SRH775 model, and there is also a slightly lower price for the RH775 model. The difference between the two is the SRH material copper tube.
Product packaging. The antenna is packed in soft plastic bags. Put it in the cardboard box.
