MyAntennas 75-10 End-fed Half-wave (EFHW) 2K plus

MyAntennas 75-10m End-fed Half-wave 2K plus antenna

I bought this antenna in the summer of 2022. This antenna is mounted in an inverted L configuration. The leg with the transformer is mounted at about 6 m on a mast near the corner of my back porch. The antenna crosses the yard to an apex about 15 m below a branch in a tree, then comes down to a base mounting point about 3 m above the ground.

This connects to the Antenna 1 input on the SPE Expert Linear 1K amplifier.

DX Commander vertical

I bought this antenna in 2021.

This antenna has resonant elements for 30, 20, 17, 15, 12, and 10 m. It is mounted in my backyard.

This connects to the Antenna 2 input on the SPE Expert Linear 1K amplifier.

I use the amplifier to switch between the two antennas.

Comet VHF/UHF

This antenna is mounted on an extendable fiberglass mast. The EFHW transformer for the HF antenna above is mounted below it.

VHF/UHF J-pole

This antenna provides input to my W3TM-11 APRS I-Gate.

Magnetic Loop

I have a W6LVP receive-only magnetic loop installed indoors. I bought this antenna used.

Paradan Dual Antenna Disconnector

The EFHW 75-10 and the DX Commander are connected to an automatic disconnect actuator by Paradan. This is not the same as air-gapping the antennas, but it does give some additional protection. The unit grounds both antennas when the power to the Flex or IC-7300 is shut off.

A workbench project is to buy a second one of these units for the VHF/UHF antennas.

Doublet

My first antenna was a doublet cut to a length that fit in my backyard, just shy of the length needed for resonant operation on 75 m.

This antenna is currently out of service.

HyPower 20m/40m fan dipole

This antenna is currently out of service.

Mobile

I have antennas mounted on both of our vehicles.

Chameleon Tactical Delta Loop

Chameleon Antennas Tactical Delta Loop (CHA TDL)

This antenna is also known as CHA TDL. I have the parts in a tripod bag I bought on Amazon.

Chameleon Antennas Modular Portable Antenna System Lite

I also have the Lite version of the CHA MPAS System.

PackTenna EFHW

I have a Packtenna EFHW cut for 20 m. This is a QRP-only antenna.

End-fed Random Wire

I have a ~10 m random wire and a counterpoise of similar length. These have spade connectors that connect to an LDG RU-9:1 Unun.

This antenna is normally part of my set of portable wire antennas, but as of r Sys.Date(), I have installed this antenna on my back porch so that I can use the Elecraft KX2 and Yaesu FRG-7 out there.

\(M^2\) SATPACK1

As of August 2023, I have acquired a SATPACK1, VHF and UHF antenna set for satellite work. The antenna is still under construction and undergoing testing. My intention is to use it for portable satellite operations or for a longer-term deployment during the winter. The extensive tree cover in and around my yard makes satellite contacts during the leafy months (April-October) almost impossible.

Alaskan Arrow antenna

I have the “Alaskan” version of the dual band (VHF/UHF) Arrow antenna. Mine has the split beam for easier transport and the built-in diplexer.

I have assembled this antenna but have not yet gotten it on the air. It’s really a beast to manipulate by hand, and I am still working on a way to physically support it using a tripod or other means.

If I can solve that problem, I would like to pair this with my Kenwood TH-72A for some FM satellite work.
