Q: Is carbon fiber conductive?

A: Yes. Unlike fiberglass, carbon fiber is mildly to moderately electrically conductive. It's not a good conductor like copper or aluminum, but it's far from an insulator.

Q: Does that matter for a mast that's just holding up my antenna?

A: It can. If a wire antenna runs directly against or taped to the mast, the mast can pick up RF energy from the wire rather than staying electrically separate from your antenna system. At low power, less than 100w, this effect is negligible. At higher power — especially with an amplifier and a tuner — enough energy can couple into the mast to heat it up.

Are replacement sections available?

A: Yes, you can find them available HERE

Overall

Lite weight but Rugged

Review by W4KG

Compact and lite weight for backpack in the Mountains for QRP operation.
Used on multi band Dipoles and End Fed Zep antennas. The 27" collapse fits nicely on the side of my backpack.

Overall

Great portable antenna mast

Review by ldailey307

The POTA33H mast works incredibly well! The mast is solidly built and can be adapted to fit nearly every portable situation. I purchased additional 3-D printed accessories for posting the mast on Etsy and the the POTA33H with these accessories makes this mast an excellent bit of kit!

Overall

Strong, light weight, easy to deploy

Review by Jim

This is a lot easier than than trying to toss a bean bag over a tree branch.

Overall

Very Strong Mast!

Review by N0MDH

This collapsible carbon fiber mast is shockingly rigid for how long it is! I plan to use this for POTA activations, but given that it's 10 meters long, I also found that I can use it to position wire antennas at my QTH. I saw it on sale, but I'd have happily paid full price for it.

Overall

Good product - recommended

Review by Steve, AB2EW

This pole extends nicely to its 33', does not bend very much at all in my 20M EFHW application, and is unbelievably light, strong and easy to handle. I previously used a 33' fiberglass pole at twice the weight. Comparing the fiberglass and carbon fiber poles, the CF does affect the resonance of my EFHW antenna. I had to slope the wire down away from the pole so the bottom was at least 3' away from the base, so my matching network and short counterpoise was not too close to the pole. With this setup, the antenna worked as expected. Moving the wire closer to the pole caused serious detuning; this did not happen with the fiberglass pole. Not a big problem, but important to know.

Overall

Great mast

Review by zdv

Met or exceeded all my expectations. Works great for getting an EFHW 30+' in the air. Flexes a little in the wind but no problems with wind loading in light to moderate wind. Easy to push up and down and so far it seems to hold its position well once set up. Lots of accessories available too - ground spikes, guy rings, etc. Definitely recommended!

Overall

Great Product

Review by AB4WS - Jack

I had the regular POTA 33 but also wanted the 33 H for heavier Antenna support. While it took almost 3 months to get, it was worth the wait. It works great. Sturdy and supports a heavier antenna in just a slightly larger package than the regular POTA 33. I give it two thumbs up!!!! 73

Overall

Great mast! Does everything right and is as advertised...

Review by BobD

Light weight, easy to deploy, great for handling heavy loads like end feds and slopers. I have two and there have been no issues. Designed just right to handle heavy lateral loads. GigaParts delivered quickly...Couldn't be happier with the manufacturer or GigaParts.

Overall

I love this thing!

Review by KR4EOD

This is my first CF telescoping mast and I love it. It’s relatively light for what it is. I have a 3D printed ring at the top for guy ropes and a bottom cap for a spike. I can easily set it up in less than 2 mins. There’s nothing I would change about it and I’d buy again if I needed another one.

Review by KB9QDI

Bought mine in April & has been fantastic so far. I mount mine in a drive over mount either with my car or in the field using the same mount I found a seller on Etsy that makes a Guy ring that fits it perfect. Combination of guy wires and the 4 holes I drilled in the amazon drive on plate to ground stake it....It don't move. I've had EFHW slopers & several verticals on it without problems. Even adding the weight of chokes & coax up the mast....no problem. I love mine. Giga Parts shipped same day & had it in Ohio in 2 days.
