Volunteer HAMS install HF antenna at Castle Hospital for emergency communications - Comet CHA250B

Volunteer HAMS install a new High frequency (HF) antenna at Adventist Health Castle / Hospital for emergency communications.

Adventist Health Castle / Hospital had a HF wire antenna but is out of commission
The hospital has gotten a new vertical HF antenna and needed help installing it.

This upgrade supports the Statewide Healthcomm net that meets the first Saturday of every month 9:00 AM HST, on 7.080, 3.835, or 5.357 USB (Ch 3 on 60 m).
All amateurs are welcome to check-in.

When a major emergency or disaster event occurs, normal modes of communications are frequently disrupted or overloaded. Storms can disrupt power grids and destroy cellular and microwave antennas. A major emergency can easily gridlock wire-line and cellular phones for an extended period.

Amateur ("Ham") Radio has provided a dependable communications pathway for many decades simply because each Ham radio station is designed to be totally self-contained and fully independent. And it has proven its value in every major emergency, including September 11, 2001, up to the present day.

The mission of Health Comm is dedicated to enhancing the emergency communications of participating institutions of the Hawaii Healthcare Association of Hawaii in times of emergency when normal means of communication are overwhelmed, failing, or non-existent. We are committed to:

Developing effective and coordinated volunteer Amateur Radio communications in support of the healthcare institutions.
Assisting the institutions with the technical requirements of Amateur Radio communications, within the guidelines of the Institution and healthcare facilities' regulations and standards.
Maintaining a relationship between healthcare institutions and Radio Amateurs that enhances each party's service to the community.
Active promotion and education of potential resources in the healthcare institutions and community.
Encouraging active and continual training and orientation of everyone involved.
Providing for the safe delivery of Amateur Radio communication in the healthcare environment.
Advancing and promoting Amateur Radio service as a whole.

We are committed to providing support utilizing well-trained and experienced professionals who volunteer to assist the healthcare institutions. We agree to develop mutual expectations and strive to exceed these expectations through professional and ethical conduct. We are flexible, adaptable, and responsive to the institutions' emergency communication needs.

Health Comm's success is due in large part to the cooperation of the healthcare institutions which we support. Each institution provides a location, purchases the needed amateur radio equipment, generally VHF/UHF, and installs the antennas and feedlines. Members of Health Comm provide needed expertise in equipment selection and antenna placement. In many cases, hams will bring along their personal equipment as a back up.

For more than 100 years, Amateur Radio — also called ham radio — has allowed people from all walks of life to experiment with electronics and communications techniques, as well as provide a free public service to their communities during a disaster or emergency, all without needing a cell phone or the Internet. 750,000 amateur radio licensees in the US, and an estimated 3 million worldwide. Throughout COVID-19, HAMS around the world have continued to be on the air practicing their skills, in part as a way to help stay connected.

http://www.earchi.org/education/ Emergency Amateur Radio Club - Hawaii would like to assist Oahu residents in obtaining or upgrading their FCC Amateur Radio licenses.


An amateur radio operator is someone who uses equipment at an amateur radio station to engage in two-way personal communications with other amateur operators on radio frequencies assigned to the amateur radio service. Amateur radio operators have been granted an amateur radio license by a governmental regulatory authority after passing an examination on applicable regulations, electronics, radio theory, and radio operation. As a component of their license, amateur radio operators are assigned a call sign that they use to identify themselves during communication.

Amateur radio operators are also known as radio amateurs or hams. The term "ham" is a nickname for amateur radio operators.
