What's the difference between the Butternut (Bencher) HF6V and HF6VX? HRO offers the 'VX for sale - not the 'V. But the 6 products listed on the Bencher "Antenna Products" web page include only the '

I'm preparing to erect a tower and antennas at a weekend retreat house that is often vacant. We haven't had any trouble leaving the place unattended to date, but I'm a bit concerned that a tall tower

I ran into an issue while examining interactions among antennas on a planned tower: tuning unused feedlines to minimize parasitic behavior of idle antenna elements. This aspect of design seems releva

I've got a run of CATV hardline I'd like to use. But on cutting into it, I see the shield is of the foil variety - with no wire. (The outside is blue; inside is shiny.) What's the best way to connect

5. [TowerTalk] Placement of coaxial matching stub at yagi feedpoint (score: 1)
Author: "Bill Conwell" <bill@conwellpdx.com>

I'm doing some EZNEC modeling - looking at converting a KLM 40m 2 element yagi to 30m. The feedpoint impedance is about 35 + j25 ohms. By shunting it with an open stub of about 100 inches of 75 ohm c

I'm toying with the idea of rebuilding my 40M3L to add some WARC bands. Has anyone done an EZNEC model of the 40M3L (or other of the M2 linearly-loaded 40m antennas)? Many thanks, /Bill, K2PO Portlan

I am toying with the idea of rebuilding a surplus M2 40M3L into a WARC antenna, with full-size elements on 30m (as well as other elements for 18m and 12m). Due to local wind and ice, Id like to truss

Is it a fair assumption that dissimilar yagis (e.g., Ed's 15m Telrex and M2) can be phased (e.g., in a vertical 2-stack) by mounting the yagis so their driven elements are vertically aligned? I have

A local estate is said to include a 160/80/40m vertical made by M2 - probably about 20 years ago. I've never heard that M2 made such a product. Can anyone confirm or offer any info? tks, /Bill, K2PO
