"I’ve had this mast for a couple weeks now. Chameleon made sure I got it before field day. I deployed it first with the spike and an EFHW which was nothing for this mast. Then I swapped the EFHW for the tactical delta loop. Then raised it up about 25’ or so. The mast remained solid. I did not need to use guy lines and we had some weather roll in for a few hours but did not affect the mast at all. I’m very happy with this mast. So far it has exceeded my expectations."

Solidly built mast
"Great design, solid build quality and locks hold mast and weight of antennas. The only problem I had was with the protective base cap. It does not stay on like is seen in YouTube product demonstrations. I’ve had to use gorilla tape to keep it from falling off. It would be great if the cap was threaded on the inside to receive the 3/8 x 24 stud"

Greatest mast I own
"This mast is serious business. I saw Bob’s (HOA HAM) review and I had to test this new mast. I am so glad that I bought one. The endless applications is a super plus. Super lightweight and sturdy enough for some serious antennas setups! I am already planning my first camping trip and two to three setups that I want to deploy. The antenna is carbon fiber and yes carbon fiber is conductive but you can adjust and results are rewarding. Just my opinion and experience with three others that I own. I also have fiberglass but the manufacturing of the CHA is just way above anything else I have used. 73"

This took awhile but totally worth the weight (pun intended)
"This mast is simply awesome. I used it at Field Day and it deploys in about a minute! In this scenario, I used it to hold up the center of a OCF (CHA OCF4020) and could not be more happy with its performance. When compared to other 34’ CFM on the market, this one sets the standard for ruggedness and ease of deployment."
— Art P. (5/5)
Very nice mast - great construction
"I was patiently waiting for a mast l like this to come back on the market. Works very well for my 8010 EFHW and I'm looking forward to other antennas. Thank you. It works great. My only wish/suggestion would be for the capability of adding other removable guy rings either higher and lower on the mast to suit more varied deployments."
— Mark K. (5/5)
Awesome Carbon Fiber Mast
"Pretty sturdy, easy to get up and going, easy to add other antenna configurations."
— Daniel L. (5/5)
Great Addition
"Great addition to my Emcomm deployment go bag"
— Edward H. (5/5)
"Great product and well manufactured"

CFM 34HD
"Great build quality."

Q&A
Heavy-Duty Portable Carbon Fiber Mast
A 33 ft 7 in portable mast for supporting documented wire antennas and carefully controlled elevated Chameleon configurations where trees or permanent structures are unavailable.
Take your antenna higher
Build a serious field station where there is no tower
The CHA CFM-34 HD gives portable operators the height to turn an open campsite, park, or emergency operating position into a capable HF station. Its heavy-duty carbon-fiber construction reaches more than 33 feet while collapsing to a transportable package.
Use it to lift documented wire-antenna feed points, support loop corners, or elevate specifically approved Chameleon vertical configurations. The result is more deployment freedom when trees, buildings, and permanent supports are unavailable - provided the published load, mounting, height, wind, and guying limits are followed.

Operator decision support
Plan the complete setup
See what this product is best suited for, what the documented setup needs, and the boundaries to confirm before deployment.
Best for
A perfect clearing without a usable tree is only a good antenna site if the operator brought a dependable way to create height.
What’s included
MAST
BASE COLLAR
BASE PROTECTIVE CAP
LOCKING CLAMP (PAIR)
What else you need
Select the approved base, sleeve, tripod, stake, or mount for the support and terrain.
Compatible with
All Chameleon portable wire antennas and MPAS READY antennas, subject to the product-specific extension and guying limits in the compatibility table
Limitations
Maximum antenna load: 6 lb (2.72 kg); reduce the load prudently for height, surface area, and wind
Do not use a Universal Clamp Mount (UCM) or Jaw Mount with the CHA CFM-34 HD
Keep the mast and attached antenna away from power lines and utility wires
Expansion options
Long Spike Mount
Surveyor Tripod Adapter
What an operator can do
Raise the feed point or center of documented wire antennas, dipoles, and end-fed systems.
Support one corner of a SKYLOOP 2.0 with each mast.
Deploy approved vertical systems at restricted mast heights when the required guying is installed.
Create a temporary field, HOA, POTA, EMCOMM, or expedition support structure without a permanent tower.
Approved bases and mounting
Ground: CHA 21-inch Long Spike Mount.
Surveyor tripod: heavy-duty surveyor tripod with CHA SURVEYOR-A.
CHA PORTA-MOUNT: Hitch, Side, Wheel, and Top mounts only when used with the approved CHA 3 IN SLEEVE kit.
Do not use: CHA UCM or CHA Jaw Mount. Stacking CFM-34 HD masts is not supported.
Compatibility and operating limits
MPAS 2.0 wire configurations: supported without mast-extension restrictions stated for the wire arrangement.
MPAS 2.0 MIL Whip + MIL EXT vertical: guy whenever any mast section is extended; extend no more than three sections, approximately 19 ft.
MPAS Lite / BV with SS17: guy whenever any section is extended; no more than three sections, approximately 19 ft.
SS25 vertical: always guy; no more than two sections, approximately 14 ft.
TDL: guy whenever any section is extended; no more than two sections, approximately 14 ft.
TD 2.0, EMCOMM II V2 / III Base, B3D 120/147: guying is recommended above three extended sections.
LEFS 8010 with 80 m extension: guy above three extended sections.
Carbon-fiber and field safety
Carbon fiber is electrically conductive. Isolate antenna wire from the mast to reduce coupling, detuning, pattern change, and loss.
Guy the mast whenever the antenna, extension height, surface area, or wind requires it; the 6 lb figure is not a blanket approval for every load.
Never deploy the mast or any antenna near power lines.
