ICOM MN-100 HF ANTENNA
ICOM MN-100 HF ANTENNA

This HF antenna matcher has been designed for ICOM HF transceivers.

To put a full size antenna on a yacht or boat is very difficult. However, this antenna matcher has been designed to put an antenna in such restrictions of space, and gives low VSWR with short antenna elements on wide frequency range of 1.5MHz to 30MHz. So, you can obtain the best performance from the transceiver.

Please NO SWAPPING Please

Super J-Pole Antenna
The 5/8 Super J-Pole Antenna

For VHF Band

Your going to like this super J-pole designed, This homemade j-pole is easy to build and sturdy, While looking for any j-pole antenna project to build. I remembered seeing a Marine antenna called the Super J-Pole in the 1988 ARRL Antenna Handbook, which claimed a 6 db gain over a quarter wave ground plane.

The Super J-Pole yields about 6dB gain + - over a 1/4 wave ground plane, by adding one 1/2 wave section to the top of the regular J Pole, with a matching section between the two which has a total length of 5/8 wavelength.

The information on this designed to give you complete construction details and to enable you to get the suggested lengths and basic information of the Super J Pole antenna. It is suggested that you use 1/2 inch tubing (aluminum) in the construction of the Super J Pole antenna for broader bandwidth.

This has a wide-range of grandstanding Standing Wave Ratio (SWR) of 1:1 on any assigned center frequency and the highest point of SWR was 1:3 of this Super J-Pole Antenna. Power Capacity 300Watts (look closely the zoom images why can capacitate high power)

The Super J-Pole antenna is a co-linear vertical consisting of a number of half wave length vertical elements separated with half-wave length stubs (Tuning stub) feed with a folded matching stub. The sub doesn't receive or radiate any energy; it is simply a way of picking off the desired feed impedance.

So, if you do not have time to assemble a homebrew antenna like this Super J-Pole Antenna Design…

Digital Repeater Controller for Two-way Radio Transciever
All in one Repeater that has Station ID, Voice ID, Announcement either in Simplex or Full Duplex Repeater, that will interface on a computer for unlimited recording system for simplex mode. This has a full capability to remote on/off your repeater system, likewise with the station ID, voice ID and Announcement using your DTMF radio.

This is only an INTERFACE CABLE with micro circuits inside COM1 connections to be connected on either one or two units of transciever radio.

Echostation Software by K1RFD included with Serial Keys. Echostation is different from Echolink for HAM Amateurs

For Customized Callsign Registration contact K1RFD.

EchoStation is a repeater-control program for Windows which makes it easy to set up a complete, fully-functional repeater or "announcement machine" using a personal computer.

EchoStation is perfect for portable and emergency use, or for clubs wishing to use a PC instead of specialized hardware to control a repeater. It also makes an excellent "store and forward" simplex repeater when connected to a single transceiver.

The software even lets you set up an "announcement machine" which plays scheduled voice announcements over your club's existing repeater, using a radio at another location, such as a home station.

Setup is as easy as installing the software, and connecting a transmitter and receiver to the PC's sound card. The transmitter can be controlled by VOX, or connected to the COM port with an interface such as DU1KJA Digital Repeater Controller. EchoStation has been fully tested DU1KJA DRC.

All standard repeater functions are supported, such as COR, CW ID, courtesy tone, forward and reverse autopatch, and control link.

If you are in the area of NCR, Please monitor and tune in to our system at 145.080Mhz.
