Review: Amazing - This project is awesome. I get great reception on my icom 52a plus anniversary or my yaesu ft-70d. The antenna is very pliable, and it works well on both of these radios. It is a great addition, swapping out from the original antenna that it comes with. For this price point, you can't go wrong. It's from a very trusted manufacturer, if you're familiar with comet, their products are by far some of the best on the market. Their innovation and technology is superior recommend this tenfold. Review: It folds down, even with the spring insert - Awesome antenna. I also bought the spring insert. One clarification, that took me forever to figure out, was that if you buy the spring insert, YES, YOU CAN STILL FOLD DOWN THE ANTENNA. I have it mounted on my FJ cruiser roof, and folded down, with a three point magnetic base, it is 6 inches high. My roof rack is 7 inches high, so perfect to provide extra protection to the antenna when going through trees and brush. Update: put it to the test recently off-roading. Smacking trees hard, with it up. most of thr time with the spring it just bent and returened to position. The three mag base I have pulled up before the antenna bent. Also, works fine when it is laying horizontal for most purposes. Obviously, straoght up it gets better reception, biy for like driving, with two vehichel communication under a mile or two, no problem on vhf, uhf, gmrs. ## Features - Dual-Band Wideband Design – Covers 140–160 MHz and 430–470 MHz for superior flexibility across amateur, commercial, and public safety radio use. - High-Gain Performance – 3.8 dBi on 2m and 6.2 dBi on 70cm bands ensures clear, strong signal transmission and reception. - Rugged Build for Mobile Use – Features a durable black fiberglass whip and stainless-steel base, perfect for on-vehicle or fixed-mount operation. - Easy Installation – NMO-style mount compatible with most mobile antenna bases; compact 38-inch height fits cars, trucks, and communication vehicles. - Trusted Quality – Designed and precision-tuned by Comet Antenna for reliable, interference-free operation in demanding communication environments. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0CHKPTCDS | | AntennaDescription | Radio | | Best Sellers Rank | #164 in Two-Way Radio Antennas #325 in Radio Antennas | | Brand | Comet | | Color | Black | | Customer Reviews | 4.8 4.8 out of 5 stars (52) | | Impedance | 50 Ohms | | Item Dimensions L x W x H | 3"L x 1"W x 6"H | | Item Weight | 4 Ounces | | Manufacturer | Comet | | Unit Count | 1.0 Count | | Warranty Description | 1 year | ## Product Details - **Antenna:** Radio - **Brand:** Comet - **Color:** Black - **Impedance:** 50 Ohms - **Manufacturer:** Comet - **Number of Items:** 1 - **Product Dimensions:** 3"L x 1"W x 6"H ## Images ![Comet CA-2X4SR Dual-Band Mobile Antenna – VHF/UHF 144/440 MHz Wideband 2m/70cm Mobile Antenna, 3.8 dB Gain, 200W Power Rating, Durable Black Finish - Image 1](https://m.media-amazon.com/images/I/41lT2QL3MVL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing *by A***K on March 7, 2025* This project is awesome.
