|450Ω vs 600Ω ladder linr to feed loop antenna using 4:1 Balun||WA2FTV||1 week, 1 day ago|
I reside in an apartment (courtyard style) with no access to outside (i.e. no balcony).
I am considering installing a large loop antenna and feeding it with either 450Ω or 600Ω ladder line from a 4:1 balun. This in turn would be fed by an antenna tuner.
Other than losses, is there any advantage of 450Ω or 600Ω ladderline?
Thank You and 73s

I am placing this note here because none of the other categories seem to be appropriate. If anybody has any information, please respond.
I am wondering if anybody knows if the QSL Organizer manufacturer/distributor MIL Industries of Panorama City, CA is still around or operating under a different name. They advertised in QST in the late 1970's and possibly the 1980's as I recall, since I received my license in 1976.
I purchased one QSL Organizer from them in the late 1970s or early 1980s. They sold an organizer (padded notebook) type album and plastic sleeve held three QSL cards on each side (six per page).
I like the format and would like to purchase a second QSL Organizer. The first one if full.
I left a note on QRZ.com in May, 2015, but nobody has responded.
Please let me know if anybody has any information.
Thank you and 73s
|High Minimum SWR (2.5 - 3.0) on 20m||WA2FTV||on 3/4/16|
I am hoping someone can provide some insight to this issue.
I have a homemade fan dipole (40m, 20m, 15, 10m) inside my apartment mounted near the ceiling with swag hooks along the perimeter of the room walls. There is no way to get an outside antenna. The wires are about 2 inches apart.
Readings below are from a MFJ 259 antenna analyzer.
On 10m, 15m and 40m, I can get a decent minimum SWR at resonance (1.25 - 1.5).
However, on 20m, the lowest SWR I can achieve is in the 2.5 -3.0 at resonance. Does anyone have a guess as to why and what might be causing this and is there a remedy?
Thank You for your input. It is appreciated very much.
Best Regards and 73s

I hope everyone is doing well.
I am down to one state to complete the W.A.S. - CW Award.
I need only South Dakota.
My CW speed is in the 5-10 WPM range. I can slow down to your speed.
I am looking for a South Dakota resident amateur that would be willing to schedule a CW QSO with me and then confirm the QSO with a QSL card (I am not on Log Book of the World yet). I will send a SASE.
I am available for a QSO from mid day to early - mid evening (16:00 - 24:00 UTC) most days. I operate stationary mobile in a local park. The bands I have available that are most likely to connect are 20m - 10m.
Looking at the propagation charts, it appears that the best time for likely success would be between 16:00 UTC and 20:00 UTC on the 14 MHz band. We could plan on using 14.125 MHz at 16:00 UTC.
I would be most appreciative if someone would step forward.
You may contact me at WA2FTV@frontier.com

|Ideas for an Apartment Balcany Antenna||WA2FTV||on 21/4/12|
I am looking for ideas for HF antennas (80-10) that would fit on an apartment balcany that measures about 9' 6" x 10'6" x 5'. The outside of the apartment complex buildings have aluminum siding.
Any thoughts would be appreciated.
