It can be used as a home QTH antenna, but don't expect full size antenna performance. With only 33 feet of wire. The developments started in the early 1970s by VEB Carl Zeiss Jena. Soliton effects in photonic crystal fibres at 850 nm. At HamCation I brought about a dozen pages of my log to Albert to show him and let him show them off. Bettina Mbius, Chief Developer of the RVS. Opt Lett 2000; 25: 2527. Description: The ULTIMAX DXTREME end-fed antenna covering 1.0 to 54 MHZ and is rated at 2KW (SSB). We will respond to you shortly. The project is straight forward, simple, and gives you emergency communications while you peddle down the road. be sure keep all parts of the antenna from metal . The right ham radio antenna for your needs will depend on several factors, such as the frequency band you want to operate in, the location and height of your antenna, the amount of space you have available for installation, and your budget. Using a krypton-filled fiber, we observe spectral broadening from 200 nm to 1.7 m at an output energy of 23 J within a single optical mode across the entire spectral bandwidth. Were a small family owned business that been in business since 2008 offering the Ham community, especially those living under HOA restrictions or any other limitations that dont allow them to have towers or big antennas the opportunity to have an antenna totally incognito at a reasonable price. Here are some comments from Yigal (K2EFG): Thank you for visiting my Amateur Radio Blog. RF Venue product distributed by Audio-TechnicaThe Diversity Fin install parts kit includes brackets and hardware for wall-mounting a Diversity Fin antenna. As a new General licensee, I spent a good deal of time researching equipment for my entrance into the world of HF. to a product via email. It is built like a tank and I am pleased with its performance. the product you have subscribed to. Well constructred! It gives more m per kg. Moving to a downsized house and property with no trees my antenna selection was poor for hf. I turned on my new IC-7300 and hoped for the best. Ultrafast supercontinuum generation in gas-filled waveguides is an enabling technology for many intriguing applications ranging from attosecond metrology towards biophotonics, with the amount of spectral broadening crucially depending on the pulse dispersion of the propagating mode. The ASTRO15 was developed exclusively by Jena-Optronik and could not have been produced without the solid dedication, immense creativity and high level of motivation of the entire company. Scheibinger R, Lpken NM, Chemnitz M, Schaarschmidt K, Kobelke J, Fallnich C, Schmidt MA. 2021 Aug 21;21(16):5640. doi: 10.3390/s21165640. Albert builds these antennas to last. I had previously been using the Ultimax 100 on 40M and wanted an upgrade.

But alas, the highest I can get anything now is 8 feet at the eaves and sloping down to a fence of about five feet. Thank you for connecting with us. The site is secure. Disclaimer. Deep-UV to Mid-IR Supercontinuum Generation driven by Mid-IR Ultrashort Pulses in a Gas-filled Hollow-core Fiber. if you want a antenna for your go bag or RV this is a good choice Stop trying say that its not working like your Beam at 100' but if you wan good an simple fast to deploy and recover and not break the bank this is it. Highly recommended. HAM RADIO ANTENNAS, ACCESSORIES OCALA, FLORIDA. Although Varney envisioned his design primarily as a 3/2 wavelength antenna for the 20 meter Amateur Radio band, radio amateurs have used the antenna for multiband use. With the help of a camera system made in Jena, the satellite construction RapidEyeeinen established a geo-information service. The first contracts for the ASTRO 15 star sensors were signed with customers from Japan and the USA. Go to amateurradio r/amateurradio Posted by mjdbb1 View community ranking In the Top 1% of largest communities on Reddit Ultimax 100 antenna and Icom 7100 I was able to get my hands on an Ultimax 100 antenna (http://www.ultimax-antennas.com/store/p1/ULTIMAX_100__.html) used by a friend. Our observation relies on the introduction of a geometric-induced resonance in the spectral vicinity of the ultrafast pump laser, outperforming gas dispersion and yielding a unique dispersion profile independent of core size, which is highly relevant for scaling input powers. After finishing his primary education and serving in the army, he studied mineralogy and geochemistry at Freiberg University of Mining and Technology. The best antenna I've used on 20 meters in the past 40 years.
