The difference would be hard to see. HF Discone Antenna 10 MHz and Up. The basic antenna structure is the bifolded monopole recently proposed as multimode high-frequency HF naval antenna which is here augmented with a top-mounted discone mainly operating in the.

Reading the ARRL Antenna Book 17th Edition I came across plans for a discone antenna that was usable for the ham bands from 40 meters through 10 meters. Notes on HF Discone Antennas L. 515 from 252 votes.

Your valuable opinion. The discone antenna is a rather unique antenna for VHF and UHF. However its still a practical option when you need coverage across multiple octaves of frequencies like high-frequency bands and low-frequency ones alike.

0005 – 2000 MHzGain. The Centre radiator includes helical trapped wire encapsulated in fiberglass to receive all HF bandsType. Apart from the list appeared below we are experts to developed military discone antenna with any.

Design of a Broadband HF Antenna for Multimode Naval CommunicationsPart II. The discone antenna or discone aerial is often used where an omnidirectional wide band or bandwidth RF antenna design is needed. Great antenna for all HFVHF and UHF.

A discone antenna derives its name from its unique appearance. 28 rows Antenna Experts offer a wide range of military discone antennas covering the HF. Radioworld HF Discone Antenna Frequency.

Professor Department of ECE K L University 2Student BTech Department of ECE K L University ABSTRACTA discone antenna is a version of a biconical antenna in which one of the cones is replaced by a disc. The discone has no gain to speak of yet can provide the user with a range of ten times the design frequency for reception and transmissions. Seeing this I decided it was time that I do a little experimenting and build one for myself.

These antennas include the bicone discone helix and oth-ers. The ARRL Antenna Book has the construction details on how to make a discone antenna for HF. Upto 15dBi over standard disconeLength.

Inexpensive discone antennas are. Extension to VHFUHF Ranges. The novelty of this approach is the feeding strategy which should Manuscript received October 10 2006.

It can be less efficient than other antennas designed for specific frequency ranges. A discone antenna placed at the top of the HF structure. The discone antenna is able to provide a bandwidth of around 101 with an omnidirectional radiation characteristic making it ideal for many uses in the VHF and UHF portion of the spectrum including as a scanner antenna.

Revised January 26 2007. 160 80 40 20 15 10 metres etc using a few simple components at a minimal cost and get great results. Each of these broadband antennas has.

20-30 MHz seems a good compromise between achievable ground wave range and a portable antenna. At frequencies where the antenna is A new design of broadband HF vertical antenna Part 1. Kandoian and brought to the attention of radio amateurs in the later 1940s the following years saw conversions of.

A quarter wave vertical is one of the most popular HF antennas because it provides low angle radiation superior to a beam or. Although most discone antennas seem to be used on the amateur radio VHFUHF bands and by public service agencies there are a few HF discone antennas in use particularly in military or government service. This is a brief video showing how to build a DIY discone antenna out of items you may have in your house.

The Discone Antenna is manufactured using high-class Aluminium alloy or chrome plated Brass material and does not require any field tuning or adjustments. The two elements can be either solid or composed of separate elements.
