The 150 on a 29 Cobra can get almost 200 watts (depends on what the radio can do barefoot). There is a big difference on the install, the 150 is more of a plug n play compared to the 75 that requires alot of parts to be removed and upgraded. Those RFX-75 & 150's might not be everybodys cup of tea, so before you flush please let me get my gloves on to retrieve it, LOL. The fins are designed to extend past the top cabinet of the radio.ДЇrom one Z-MAN to another.hello. (coming soon).ДҐ-3/8' wide (across the back panel of the radio) x 2-1/4' deep (how far it sticks off the back of the radio) x 2-1/2' tall. The RFX150 fins are drilled and channeled for easy mounting of the optional fan kit. Heavy-Duty Power Cord with SAE Connectors and weatherproof fuse holder The familiar push-pull design features time-tested components such as broadband transformers and The RFX150 uses a matched pair of ERF7530 high power MOSFET RF transistors running Class AB. Latest Technology MOSFETвЂ™s in an Old School Circuit The fins extend past the transceiverвЂ™s top cabinet to allow increased air flow to the heat sink. That is why the RFX150 features a radically unique design with vertical upward pointing cooling fins. So why would anyone design a heat sink with horizontal or downward pointing fins? In lower power applications this may be okay, but when dealing with hundreds of watts in a mobile environment you need every advantage possible. Unique Vertical Fin Design Maximizes Heat Dissipation. The RFX150 uses a matched pair of ERF7530 75W RF Power MOSFET from EKL Components The RFX150 does not work independently, but it is an integral part from an amateur transceiver and is available for repair and replacement purposes.

The RFX150 includes the RF final output stages and low pass Filter section for a 10 meter mobile amateur The RFX150 is a replacement part for 10 meter amateur transceivers.

How good is the rfx 150 final
