Whipping Up Some Contacts

In my last post, I mentioned how I damaged the telescopic whip, which is part of my Gabil GRA-7350TC antenna. The replacement telescopic whip has a long lead time, so I ordered a carbon fiber whip from Gabil in the meantime. Less than 24 hours after Amazon delivered it, I put the new whip to the test.

The new whip is the Gabil GRA-CFP2600 carbon fiber whip. Weighing in at just 78 grams (2.75 ounces), it’s a lightweight whip that breaks down into five separate sections. Fully assembled, it measures 248.4 cm (8 feet, 1.8 inches). That’s a tad longer than the stock whip. The sections are thin, but rigid. They slide together with a friction fit and make a distinctive “pop” when separated. 

To try it out, I headed over to Marsh Creek State Park (US-1380, KFF-1380) near one of the boat launches. Being a sunny and brisk October day, the parking lot was jam-packed with folks taking advantage of the weather. My original plan was to operate from a picnic table next to the lake. Since someone was already using the table, I operated from the truck. 

To try out the new whip, I used a mag mount on the roof of the truck and ran the coax to my KH1 inside the truck. Using an antenna analyzer, I easily tuned up the antenna on 40M and got started. The band was as busy as the park. There were a couple of contests going on besides the large number of POTA stations I heard.

 After finding an open frequency, I started calling CQ. The carbon fiber whip seemed to work well. I logged my first 10 contacts in just 10 minutes. After about 15 minutes, I was getting a headache from hearing stations on adjacent frequencies. I opted to seek refuge in the calmer waters of 30M. I picked up several more contacts before shutting down. After 40 minutes I had 22 contacts with four park-to-park contacts. I had P2P contacts on two bands from both WC1D and NI8W. Thanks, guys!

Before packing up the antenna, I did a quick check of the SWR on 20M and 17M. No issues tuning up on those bands. In my haste to pack up, however, I neglected to take a picture of the antenna installation. So, you’ll just have to use your imagination to picture a thin, black, eight-foot whip on a magnetic mount. 

This carbon fiber whip has been on the market for a while, so I won’t bore you with a detailed review. YouTube has several reviews, and the Gabil website features two of them. However, there are a couple of pros and cons from my first outing with it.

Pros:

• It’s super lightweight
• Goes together quickly
• Seems more rugged than the original telescopic whip
• On the air, it seems to work as well as other short whips I have used. Certainly, as well as the original telescopic whip.

Cons:

• Broken down, the pieces are significantly longer than the rest of the GRA-7350TC components. I have to pack them separately from the rest of the Gabil GRA-7350TC components.
• Speaking of packing… Other than the cardboard tube it ships in, there is nothing provided to store the pieces in. I’m still thinking about how I will pack and transport this whip in the field. I’m thinking about buying a tent pole bag to carry it in. If any GRA-CFP2600 owners have suggestions, I’m all ears. 

The GRA-CFP2600 whip is a novel design from the good folks at Gabil. It certainly has the high quality that is typical of their other products. 

As always, this blog has no advertisers or sponsors. I bought the GRA-CFP2600 with my own funds.
