Made in Taiwan with durable adhesive resin magnet and copper sheet, it supports up to 500W SSB power and installs easily on metal vehicle surfaces without modification. Ideal for amateur radio enthusiasts seeking stronger, more efficient mobile HF transmissions. ## Description desertcart.com: GABIL GRA-MAT50 HF Ground Enhancement Mat for Mobile HF Antennas | Supports RF ground coupling for mobile HF antennas, 7–50 MHz, Made in Taiwan : Industrial & Scientific Review: PORTABLE - EASY TO USE - INEXPENSIVE - Quite functional, works well to adjust a mobile antenna's ground plain and general experimentation. The magnetic pad sticks well to my car for good contact. It's easy to install and remove so it's portable. I've used mine for weeks now and I must say that I have seen changes in signal strength based on frequency and antenna. Do your research first. Review: Improved my SWR - I use the GRA-MAT50 MK2 with my Yaesu ATAS-120A antenna on a mag mount in the center of my minivan roof. Before connecting the GRA-MAT50 to the antenna, my SWR on 40 meters was about 2.3:1, which is not terrible, but could be better. Once I connected the GRA-MAT50 to the antenna, my SWR on 40 meters went down to about 1.4:1, which is pretty good. I did not notice any improvement in SWR on other bands (10,12,15,17,and 20 meters) because the Yaesu ATAS-120A is able to tune those bands good on its own without the GRA-MAT50. But the improvement on 40 meters makes this purchase worth it. A friend of mine also uses the Yaesu ATAS-120A on a mag mount and he has the same higher SWR problem on 40 meters. So he is considering the purchase of the GRA-MAT50 to help with 40 meter SWR. Even though the GRA-MAT50 did not make a difference on bands other than 40 meters with my Yaesu ATAS-120A, it might help with my transmit signal somewhat anyway by creating a more efficient counterpoise by helping to increase the capacitive coupling of the antenna to the vehicle.. I have another mag mount antenna, (Hustler MO-2 with resonators) but I have not tested the GRA-MAT50 with that antenna. If I do test it with that antenna, I will submit that review. I would think that the GRA-MAT50 may probably help with that antenna too since the bandwidth with the Hustler MO-2 on a mag mount is quite narrow on 40 meters, and the internal tuner of the radio is not able to get the SWR real low on 40 meters. So, what is generally known about a mag mount antenna on the HF bands, the lower in frequency that you get, the less effective a mag mount antenna can be, most notably 7 mHz or lower. But the GRA-MAT50 can help with that. Bottom line, I recommend the GRA-MAT50, especially for 40 meters. ## Features - SUPPORTS MOBILE HF GROUNDING Designed to help improve RF ground coupling in compatible mobile HF antenna installations. - FOR 7–50 MHz OPERATION Suitable for HF mobile systems operating from 7 to 50 MHz. Two mats can be used to increase the effective coupling area for lower-frequency applications. - SIMPLE TO INSTALL Flexible adhesive magnetic design mounts easily to suitable metal vehicle surfaces without modifying the antenna system. - COMPACT & DURABLE Measures 80 Γ— 195 mm with a 30 cm lead wire. Built for portable and mobile amateur radio operation. - MADE IN TAIWAN Constructed with adhesive resin magnet and copper sheet. Rated up to 500 W SSB or 200 W FM/CW under specified operating conditions. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BVTJT1RJ | | Antenna | Radio | | AntennaDescription | Radio | | Best Sellers Rank | #225,122 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #96 in Electrosurgery Grounding Pads | | Brand | Gabil | | Color | black | | Customer Reviews | 4.2 out of 5 stars 58 Reviews | | Impedance | 50 ohm | | Manufacturer | G GABIL RADIO TAIWAN 2006 | | Model Number | GRA-MAT50 | | Number of Channels | 1 | | Number of Items | 1 | | Number of Packs | 1 | | UPC | 631851845818 | | Unit Count | 1 Count | | Warranty Description | non | ## Product Details - **Antenna:** Radio - **Brand:** Gabil - **Color:** black - **Impedance:** 50 Ohms - **Manufacturer:** G GABIL RADIO TAIWAN 2006 - **Number of Channels:** 1 - **Number of Items:** 1 - **UPC:** 631851845818 ## Images ![GABIL GRA-MAT50 HF Ground Enhancement Mat for Mobile HF Antennas - Image 1](https://m.media-amazon.com/images/I/41xngsKMKvL.jpg) ![GABIL GRA-MAT50 HF Ground Enhancement Mat for Mobile HF Antennas - Image 2](https://m.media-amazon.com/images/I/41ywhj0AXxL.jpg) ![GABIL GRA-MAT50 HF Ground Enhancement Mat for Mobile HF Antennas - Image 3](https://m.media-amazon.com/images/I/51lIkTPwp7L.jpg) ![GABIL GRA-MAT50 HF Ground Enhancement Mat for Mobile HF Antennas - Image 4](https://m.media-amazon.com/images/I/61n8YX8c2sL.jpg) ![GABIL GRA-MAT50 HF Ground Enhancement Mat for Mobile HF Antennas - Image 5](https://m.media-amazon.com/images/I/51ku5VFYl+L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ PORTABLE - EASY TO USE - INEXPENSIVE *by B***F on May 20, 2025* Quite functional, works well to adjust a mobile antenna's ground plain and general experimentation.
