- Transmission Lines
- Whenever you choose a coax feedline, the frequency of operation is a very important consideration. Over the operating bandwidth of the coax the VSWR is low, typically 1.2:1 or better. Insertion loss is also an important parameter. It is usually specified in dB/foot and is a linear relationship.

- A two dollar helical hf portable antenna
- Here is an easily transportable vertical antenna for 20 meters collapsible to 4 feet that costs about $2.00 to make.
This was created as a fun project to demonstrate how to enjoy operating HF in the field with a home-made portable antenna without spending a ton of money.
Bev AH6NF (YL) made this antenna, tuned and ready to operate in less than one hour

- Understanding Standing Wave Ratios SWR
- We worry a lot about Standing Wave Ratio (SWR) in amateur radio since SWR is one indication of how well our antenna system is working. Most HF transceivers and antenna tuners have built in SWR meters. SWR is a measure of a transceiver'
s output power verses the portion of that power reflected by the antenna system

- IK-STIC 2 vertical multiband antenna
- The IK-STIC 2 is a vertical, all band, antenna that is over 25 feet tall yet weighs under 5 pounds.
Based on a telescopic pipe or a fiberglass fishing pole, using a tuner it can easily cover the amateur radio HF bands from 40 - 10 Meters

- VectorFox is a software born to incorporate a PC into the fox hunting environment. VectorFox is able to take inputs from up to 5 sources, such as a 2m beam, a 2m signal meter, a TDOA, etc, and display the results on the screen. VectorFox also accepts Agrelo inputs. From these results the operator can choose which indication is best and have a line drawn on the map in the direction of the signal.

- A low power 3.5MHz ARDF transmitter
- This low power transmitter is developed for ARDF exercising purposes but of course can be used as super QRP transmitter either. With 1 or 2 meter wire as antenna and a ARDF receiver with ferrite-rod antenna the range is about 100m but with better antennas and a 'real' receiver the range is probably much larger.
